Organic electrochemical transistors for biosensing

Organic and Hybrid Sensors and Bioelectronics XIV, 2021
Conjugated polymers provide a unique toolbox for establishing electrical communication with biological systems. In the first half of this talk, I will introduce the type of conjugated polymers used at the biological interface. I will then show how we designed organic electrochemical transistors (OECTs) for protein detection at the physical limit and ...

Automated and ultrasensitive point-of-care glycoprotein detection using boronate-affinity enhanced organic electrochemical transistor patch.

Biosensors & bioelectronics
Quantifying trace glycoproteins in biofluids requires ultrasensitive components, but feedback is not available in the current portable platforms of point-of-care (POC) diagnosis technologies.

Ion-Sensitive Properties of Organic Electrochemical Transistors

ACS Applied Materials & Interfaces, 2010
Ion-sensitive properties of organic electrochemical transistors (OECT) based on Poly(3,4-ethylenedioxythiophene): poly(styrene sulfonic acid) (PEDOT:PSS) have been systematically studied for the first time. It has been found that the transfer curve (I(DS)-V(G)) of an OECT shifts to lower gate voltage horizontally with the increase of the concentration ...

Neuromorphic Functions in PEDOT:PSS Organic Electrochemical Transistors

Advanced Materials, 2015
Depressive short-term synaptic plasticity functions are implemented with a simple polymer poly(3,4ethylenedioxythiophene):poly(styrene sulfonate) (PSS) organic electrochemical transistor device. These functions are a first step toward the realization of organic-based neuroinspired platforms with spatiotemporal information processing capabilities.

Advances in organic transistor-based biosensors: from organic electrochemical transistors to electrolyte-gated organic field-effect transistors

Analytical and Bioanalytical Chemistry, 2011
Organic electronics have, over the past two decades, developed into an exciting area of research and technology to replace classic inorganic semiconductors. Organic photovoltaics, light-emitting diodes, and thin-film transistors are already well developed and are currently being commercialized for a variety of applications.
