Transistors organiques ultra-sensibles : une avancée pour la détection de biomarqueurs Pour diagnostiquer ou surveiller une maladie, pouvoir détecter des quantités infimes de biomarqueurs, les indicateurs biologi

➡️ Press release ⬅️ How does our work at @icpees.bsky.social contribute improving biosensors for medical applications? This question is answered by the @cnrs-alsace.bsky.social press release which presents the improvements reported in our last article on high-performance OECTs.

Over Tenfold Increase in Current Amplification Due to Anisotropic Polymer Chain Alignment in Organic Electrochemical Transistors How to boost the IDS output of an OECT? Anisotropic polymer alignment along the channel direction enables a 13-fold increase in IDS. Such channel engineering opens the door to unprecedented signal am...

A new paper is out in Adv. Mater, in collaboration with N. Banerji's group (UniBern)! Upon anisotropic alignment of the polymeric OECT channel, we increased the IDS reaching unprecedented signal amplification, faster ON/OFF switching and higher stability.
