Organic Electrochemical Transistors for Clinical Applications
Advanced Healthcare Materials, 2014The ability of organic electrochemical transistors is explored to record human electrophysiological signals of clinical relevance. An organic electrochemical transistor (OECT) that shows a high (>1 mS) transconductance at zero applied gate voltage is used, necessitating only one power supply to bias the drain, while the gate circuit is driven by ...

Validation of the organic electrochemical transistor for in vitro toxicology
Biochimica et Biophysica Acta (BBA) - General Subjects, 2013The gastrointestinal epithelium provides a physical and biochemical barrier to the passage of ions and small molecules; however this barrier may be breached by pathogens and toxins. The effect of individual pathogens/toxins on the intestinal epithelium has been well characterized: they disrupt barrier tissue in a variety of ways, such as by targeting ...
