Our expansive review paper “Conjugated Polymers for Assessing and Controlling Biological Functions” was published in Advanced Materials today. The article will be part of an issue dedicated to Professor Olle Inganäs (Linköping University) on the occasion of his Professor Emeritus title. Together with A.L. Rutz and G.G. Malliaras at the University of Cambridge, we discuss the use of conjugated polymer materials in five biologically oriented research topics: electrophysiology, tissue engineering, drug release, biosensing, and molecular bioelectronics.
