A new article titled ‘P-type accumulation mode organic electrochemical transistor biosensor for xanthine detection in fish‘ has been published in Biosensors and Bioelectronics.
In our latest research, we developed an OECT-based biosensor with a p-type polymer bithiophene–thienothiophene copolymer with tetraethylene glycol side chains, p(g42T-TT), as the channel material. The xanthine biosensor aims to monitor the quality of meat and fish products, providing freshness predictions with respect to pre-defined expiration dates. The biosensor detects the xanthine level, which reflects the degradation of meat and fish products. The results show the time-dependent xanthine in fish samples from day 0 to day 6.
