Diabetes is one of the most common problems leading to kidney failure and other deadly medical conditions if not monitored properly. The pre-existing techniques for monitoring diabetes utilize enzymes, which makes the technique costly, sophisticated, and temperature-dependent storage restricts its broad range utilization necessitating label-free detection. The present research deals with successful non-enzymatic detection of glucose using CuO/MXenes as a non-enzymatic probe and extended-gate OFETs as a transducer and a signal detector.
Biogenic CuO nanoparticles were first synthesized using Annona squamosa seed extract. CuO/MXenes were then synthesized by adopting an ex-situ synthesis approach. The CuO/MXenes nano-composites were characterized by various techniques and then screen printed on ITO glass to use as a sensing probe and extended gate of the organic field-effect transistor (OFET). The OFETs were fabricated by utilizing regioregular poly(3-hexylthiophene) [RR-P3HT] as an organic semiconductor in the bottom gate top contact device architecture and utilized as a transducer by connecting its gate to the sensing electrode using copper wire.
