Come find us and let’s connect!
As the spring semester comes to a close, we are taking a moment to reflect on the many milestones our group has celebrated. May has been a month of transformation at Herland Lab, and we are proud to celebrate the brilliant minds who have recently completed important chapters in their journeys with us! From defending a PhD to wrapping up MSc research projects that pushed boundaries across disciplines, here is our story.
On May 9th, our PhD student Saumey Jain successfully defended his thesis: “Bridging Scales – Nanofabrication and Microfluidics for Sensing and Cell Culture Platforms“. His research journey explored the intersection of physics, engineering, and biology; from the development of nanoscale biosensing platforms such as nanogaps and solid-state nanopores, to applying microfabrication techniques for improving iPSC-derived neuron differentiation.
He now brings that scientific depth into the innovation pipeline as he joins HØIBERG (European Patent Attorneys), helping other researchers bring their technologies to life. Good luck, Saumey, and thank you for being the backbone of our lab!
We also want to give a standing ovation to our MSc students, who just wrapped up their projects with impressive progress and dedication, both in the lab and during their final presentations! Each project reflects the interdisciplinary spirit we strive for. Here are just a few of the exciting directions they pursued:
Gabriel Gyllensting (Karolinska Institutet, Medical Program): Organ-on-Chip Model for BBB Invasion of E. coli in Bacterial Meningitis

We are proud to share that our group leader, Anna Herland, has been appointed full professor in Hybrid Bioelectric Systems at KTH during the 2024 Professorial Installation Ceremony! KTH highlighted Professor Herland’s research in a recent video feature, which can be checked out here: [Link to KTH website]
Professor Herland’s research focuses on the development of Organ-on-Chip (OoC) systems, microphysiological platforms that replicate human tissue environments using patient-specific hiPSC-derived cells. These systems are integrated with organic bioelectronics to enable real-time functional assessments and dynamic readouts of tissue responses.
Her vision has shaped the foundation of our lab’s interdisciplinary approach, combining stem cell engineering, microfluidics, and organic electronics to explore how the brain and body interact at the cellular level. A major area of our work is building advanced models of the human neurovascular unit, where we study neuronal activity, metabolic dynamics, and blood-brain barrier function in health and disease. These systems are powerful tools laying the groundwork for more predictive drug testing and new tools in personalised medicine.
The group gathered to celebrate this milestone with a small lab event, complete with professor sashes and celebratory crowns!
One of our collaborative works with Karolinska University Hospital was featured in an interview by KTH, with the theme of ‘3D Printing and Polymer Chemistry Revolutionize Diabetes Treatment‘. This project has been supported by the Health, Medicine, and Technology (HMT) initiative from KTH and Region Stockholm.
Together with Prof. Lisa Juntti-Berggren from the Signal Transduction research group at KI, we are developing a novel method to improve pancreatic islet transplantation into the anterior chamber of the eye (ACE). Our doctoral student, Jessika Jessika, is currently leading the exploratory phase to address the challenges in manufacturing drug-releasing microstructure along with some of the MSc students in the group.

A new article titled ‘P-type accumulation mode organic electrochemical transistor biosensor for xanthine detection in fish‘ has been published in Biosensors and Bioelectronics.
In our latest research, we developed an OECT-based biosensor with a p-type polymer bithiophene–thienothiophene copolymer with tetraethylene glycol side chains, p(g42T-TT), as the channel material. The xanthine biosensor aims to monitor the quality of meat and fish products, providing freshness predictions with respect to pre-defined expiration dates. The biosensor detects the xanthine level, which reflects the degradation of meat and fish products. The results show the time-dependent xanthine in fish samples from day 0 to day 6.
Our lab is excited to announce our participation in a groundbreaking project, ‘Developing a first-in-class vascularized Gut-Brain-Axis-on-chip platform for accelerating research and drug discovery (GBA-CONNECT)‘. In collaboration with Dr.biol. Artūrs Ābols at the Latvian Biomedical Research and Study Centre (BMC), Cellboxlab, and other esteemed partners, the project will run up to mid-2026.
This initiative, funded by the Eureka Eurostars program, aims to develop a cutting-edge Gut-Brain-Axis (GBA) on-chip platform integrating advanced organ-on-chip technologies, including in vitro blood-brain barriers and co-cultured anaerobic microbiota. Next-generation hardware for automated culturing, monitoring, and analysis will also be investigated to address critical gaps in current drug discovery methods. This platform will provide new insights into drug absorption, blood-brain barrier permeability, and drug toxicity evaluation to enhance our understanding of the Gut-Brain-Axis, with the potential to revolutionise therapeutic development for neurological and mental health conditions.
Stay tuned for more updates on the progress of this exciting research!
The latest article ‘In Situ Functionalization of Polar Polythiophene-Based Organic Electrochemical Transistor to Interface In Vitro Models‘ has been published in ACS Applied Materials & Interfaces.
In our latest research, we present the new conjugated polymer p(g42T-T)-8% OH, a promising material for simplifying the interface between biological systems and electronics. This polymer contains hydroxyl groups, enabling straightforward chemical modifications to control cell adhesion and growth on its surface. We demonstrate the fabrication of organic electrochemical transistors (OECTs) using p(g42T-T)-8% OH, which were successfully employed to monitor the formation of cell barriers in vitro. This research provides a valuable tool for studying biological systems and offers a pathway for developing customizable bioelectronic devices that more effectively interface with biological tissues.
Our work on ‘Electromigrated Gold Nanogap Tunnel Junction Arrays: Fabrication and Electrical Behavior in Liquid and Gaseous Media‘ has been published in ACS Applied Materials & Interfaces. The associated work on the measurement setup has also been published in Review of Scientific Instruments, titled ‘High-bandwidth low-current measurement system for automated and scalable probing of tunnel junctions in liquids‘.
The first article introduces feedback-controlled electromigration to fabricate stable gold nanogap tunnel junctions for single-molecule sensors capable of operating robustly across various liquid and gaseous environments. We systematically examine both the electrical behaviour and the yield of junction formation across different media, with attention to how specific operating conditions influence stability and performance. The findings not only advance our understanding of tunnel junction scalability and production but also enhance the potential for integrating these sensors into practical, compact devices.
In the second article, we describe an innovative measurement setup that supports high-bandwidth (>10 kHz) and low-current (pA–nA) measurements, crucial for the effective probing of these tunnel junctions. By integrating a custom two-terminal probe with a 100 kHz bandwidth amplifier and automating the data acquisition within a noise-reducing Faraday cage, we have streamlined the scalability and improved the precision of these measurements.
A new perspective article titled Human In Vitro Models of Neuroenergetics and Neurometabolic Disturbances: Current Advances and Clinical Perspectives‘ has now been published in Stem Cells Translational Medicine.
Understanding the mechanism behind CNS energy metabolism and their role on brain function is crucial to answer the relevant questions in human neurological conditions. Establishing a physiologically relevant in vitro models of neuroenergetics requires comprehensive understanding of different cell types processes and interaction, also various metabolic pathways and regulatory mechanisms. The article highlights important keypoints in the development of human in vitro model of neuroenergetics, covering both the biology and technology perspectives.
Our latest work, ‘On-Chip Neural Induction Boosts Neural Stem Cell Commitment: Toward a Pipeline for iPSC-Based Therapies’, has been published in Advanced Science and featured in KTH press release.
The work has successfully demonstrated the first microfluidics platform to redirect iPSCs toward becoming neural stem cells. Here, a simple and cost-efficient microfluidic platform is developed to reprogram human fibroblasts into induced pluripotent stem cells (iPSCs) and further differentiate them into neural stem cells with boosted neural stem cell generation commitment. With further customization, the platform could be adapted for differentiation into other cell types, marking an important step towards making personalized cell-based therapies for Alzheimer’s and Parkinson’s disease more accessible.
The work ‘Mixing Insulating Commodity Polymers with Semiconducting n-type Polymers Enables High-Performance Electrochemical Transistors’ has been published in Advanced Materials and featured in IEEE Spectrum.
Blending polystyrene with n-type conjugated polymer p(N-T) is demonstrated to produce high-performing OECT with drastically reduced conjugated polymer required to achieve functionality. By using commodity polymers such as polystyrene, the organic semiconductors’ material consumption could then be used sparsely, leading to the cost-effective and sustainable development of organic transistors.
The published article from Advanced Science titled ‘Cleanroom-Free Direct Laser Micropatterning of Polymers for Organic Electrochemical Transistors in Logic Circuits and Glucose Biosensors’ has been featured in the KTH press release on Via TT news channel.
The established protocols aim to be a sustainable alternative to perform device fabrication with reduced dependency on cleanroom facilities, which involve a significant amount of solvents and chemical developer baths in the process. The work also demonstrated the possibility of performing rapid prototyping with micropatterning based on ultrafast laser technology to manufacture different types of organic bioelectronics devices.
A new perspective article titled ‘From animal testing to in vitro systems: advancing standardization in microphysiological systems‘ was published in Lab on a Chip today.
Microphysiological systems, like organ-on-a-chip models, show promise for healthcare and drug development. Clear standards are needed for their effective use. Collaborative efforts are underway to establish these standards, with input from regulators, academia, and industry. This framework aims to foster discussion and enhance the impact of microphysiological systems.
Our latest work presenting a cleanroom-free method to micropattern polymers for fabricating organic electrochemical transistors (OECTs) has now been published in Advanced Science.
By employing femtosecond laser technology, we achieved high-resolution patterning of insulating and (semi)conducting polymers with a resolution down to 2 micrometers, providing a cost-effective alternative to traditional cleanroom-based microfabrication methods. This versatile and scalable approach is particularly well-suited for prototyping, therefore accelerating OECT research and facilitating their widespread use in applications such as biosensors or logic gates. Our work marks a significant step towards more accessible and efficient OECT fabrication methods, offering potential benefits for a variety of advanced organic bioelectronic applications.
A new paper titled ‘3D-Printed Biohybrid Microstructures Enable Transplantation and Vascularization of Microtissues in the Anterior Chamber of the Eye‘ was published in Advanced Materials today.
This study introduces a pioneering approach for transplanting biohybrid microstructures into the anterior chamber of the eye. This technique combines biological cells with sensors to detect subtle physiological responses with precision. Overcoming challenges related to pupillary dynamics, the method ensures secure transplantation and prolonged functionality of microstructures housing pancreatic islets. Even more striking, these islets develop a blood supply, offering exciting prospects for improved disease modeling, treatment efficacy, and engineered tissue vascularization. This breakthrough redefines possibilities in bioengineering and regenerative medicine, providing hope for enhanced medical treatments.
The Herland Lab spent an intense and enjoyable week in Berlin, Germany at Microphysiological Society World Summit which was held together with the European Organ-on-Chip conference.
Sebastian gave a talk in the session on “Microfabrication, Instrumentation & Sensors” and Laura presented the work done as a part of master thesis in the session on “MPS for Vascularization”. Julia, Rohollah, Saumey, and Begum presented posters with their latest research results.
Julia, Begum, Sebastian and Laura were also awarded travel grants.
A new paper titled ‘Probabilistic cell seeding and non-autofluorescent 3D-printed structures as scalable approach for multi-level co-culture modeling‘ was published in Materials Today Bio today.
In this work, we have developed a 3D-printed platform that enables precise control and in-depth study of the interaction between astrocytes and neurons. To achieve this, we utilized a commercially available printing resin IP-Visio (Nanoscribe), with non-autofluorescent and non-cytotoxic properties. We successfully printed a neurite guidance platform, which served as a guiding structure for the outgrowth of neurites from neurons. By employing a probabilistic two-step cell seeding approach, we were then able to control the interaction points between neurons and astrocytes. This innovative approach simplifies the modeling of complex brain interactions, thereby facilitating further advancements in biomedical research and enhancing our understanding of the human brain.
Prof. Anna Herland gave the plenary talk at The International Society for Stem Cell Research‘s Annual Meeting 2023, 14-17th June 2023 in Boston on next-generation in-vitro models for modeling development and disease.
Herland Lab participated at the Swedish Microfluidics in Life Science conference in Stockholm on the 30th and 31st of May. Laura and Rohollah had oral presentations, whereas Yunfan, Monika, and Salem presented their research as posters. It was a great opportunity to network with the microfluidics network in Sweden as well as the neighboring countries.
Laura Benito-Zarza pitched her master thesis work today during the Nordic Organ-on-Chip networking event and won one of the best pitch awards, consisting of a travel grant in the Nordics to expand her network and experience in the Organ-on-Chip field. She is supervised by Dr. Julia Rogal and Dr. Alessandro Enrico and working to develop a hiPSC-derived microvascularized tissue model to recapitulate in vivo complexity for the study and treatment of complex diseases, such as Parkinson’s and Alzheimer’s.
Congratulations Laura!
Dr. Erica Zeglio was admitted as a Docent in Bioelectronic Materials at KTH. She gave the docent lecture on ‘Organic bioelectronics: from sustainable materials chemistry to the interface with biology.’ The docentship in the Swedish system means she can supervise and be an opponent for a PhD candidate and is not supposed to lose badly.
A new paper titled ‘Astrocyte 3D culture and bioprinting using peptide functionalized hyaluronan hydrogels‘ was published in Science and Technology of Advanced Materials today.
This work highlights the development of peptide functionalized hyaluronan hydrogels for bioprinting. The study utilized neuroblastoma (SH-SY5Y) and glioblastoma (U87) cell lines and human fetal primary astrocytes (FPA) with a modular hyaluronan-based hydrogel system. It was observed that FPA had a higher degree of interaction with the hyaluronan-based gels compared to the cell lines. These engineered hydrogels enable the possibilities to bioprint, culture and maintain FPA and can thus facilitate the development of more elaborate neural and astrocytic tissue and disease models.
Prof. Anna Herland and Dr. Erica Zeglio are awarded grants from the Swedish Research Council (Vetenskaprådet).
All new drug candidates need to be evaluated for central nervous system (brain) penetration and sideeffects. Unfortunately, and especially for new drug types, the testing methods do not show how the drugs will work in humans. Here, we focus on developing and validating human functional Organ-on-Chip models of the brain and its vasculature. In this work, which is a collaboration with AstraZeneca around the theme to reduce and refine animal experiments, we especially focus on human specific drugs including viral vectors and protein or peptide-based drugs.
2. 2D and 3D in vitro models with organic electronic interfaces to electrogenic cells (PI: Prof. Anna Herland, co PIs: Prof. Max Hamedi (KTH), Prof. Frank Nikalus (KTH) and Dr. Erica Zeglio (KTH))
Electrodes are needed to stimulate and measure on electrically active tissues, such as the heart and brain. Electrodes are specifically used in electrophysiology, the studies of electrically active cells outside the body. This is an essential method in drug development and toxicity studies.
The main goal in this project is to create new methods to carry out electrophysiology in 3D and microfluidic cell culture, so called Organ-on-Chips. We will combine the development of new polymer materials, new transistor designs, and new fabrication methods for electroactivity measurements in 2D and 3D systems.
3. Biodegradable electronic polymers: from device components to in vivo monitoring technologies (VR Starting Grant, Dr. Erica Zeglio)
Temporary implants are currently based on electronics that dissolve in contact with water, limiting their application in contact with (water-based) biological fluids. With the project “Biodegradable electronic polymers: from device components to in vivo monitoring technologies”, the Team led by Dr. Zeglio will investigate device components that are stable in contact with water and degrade into nontoxic products by the action of living cells.
The article titled “Metabolic Assessment of Human Induced Pluripotent Stem Cells-Derived Astrocytes and Fetal Primary Astrocytes: Lactate and Glucose Turnover” was published in Biosensors today.
Astrocytes are one of the key cell types in brain for energy metabolism. In this research article, the metabolic parameters of astrocytes derived from two common sources including induced pluripotent stem cells (hiPSCs) and human fetal primary astrocytes (HFAs) were studied in a defined media. The glucose uptake and lactate production in astrocytes derived from hiPSC to HFA were compared using a flow-through biosensor. The study concluded that hiPSC-derived astrocytes are as glycogenic as their fetal counterparts, but their normalized metabolic turnover is lower.
