A flexible biosensor was developed by researchers at Pennsylvania State University (Penn State) and several universities in China to perform continuous, wireless monitoring of nitric oxide, a biomarker associated with inflammation, in rabbits.
The device is comprised of flexible and biocompatible organic electrochemical transistors and a channel made of the polymer PEDOT:PSS.
The sensor can transmit nitric oxide levels to a smartphone app via Bluetooth.
Penn State's Huanyu "Larry" Cheng said, "The reference-free sensor with a miniaturized active sensing region enables nitric oxide detection with improved spatial resolution compared with previously reported electrochemical nitric oxide sensors, which could allow the mapping of electrochemical signals to offer comprehensive diagnostic information."
