Hydrogels: Room‐Temperature‐Formed PEDOT:PSS Hydrogels Enable Injectable, Soft, and Healable Organic Bioelectronics (Adv. Mater. 1/2020)

In article number 1904752, Shiming Zhang, Ali Khademhosseini, and co-workers demonstrate that an injectable conducting polymer poly(3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) hydrogel fiber can be achieved by crosslinking a PEDOT:PSS suspension at room temperature in a tube. The hydrogel fiber can be extruded by pressurizing the tube without affecting its structural integrity. The fiber can be further used as a channel material for developing hydrogel-based organic electrochemical transistors, relevant for organic and hydrogel bioelectronics.
