In this contribution, we deal with PEDOT: PSS organic electrochemical transistors (OECTs),
which pose a perspective device for biosensing applications. We manufactured two
transistors with electrolysis prepared Ag/AgCl electrode, and commercial one. Commercial
one, reached better current stability, therefore we propose PEDOT: PSS (GOPS)
benchmarking according to it. PEDOT: PSS films were prepared by perspective inkjet
printing and crosslinked by GOPS. There is still a space for optimization to reach biosensing …

Organic electrochemical transistors (OECT) have been demonstrated and extensively
studied as an effective platform for the design of chemical and biological electronic sensing
applications, based on their advantages on low-voltage operation, good biocompatibility
and interaction with aqueous medium, facile chemical modification of semiconductors and
electrodes, and applicability on varied substrates including flexible plastics.[1] However,
conventional OECTs are normally fabricated in the scale of millimeter or larger, resulting in a …
