Abstract

Laser ablated tin oxide quantum dots (SnO2 QDs similar to 1-5 nm) uniformly dispersed in a colloidal solution have been electrophoretically deposited onto indium-tin-oxide (ITO) glass for immobilization of xanthine oxidase (XOx) for fabrication of fish freshness biosensor. The results of electrochemical response studies conducted on XOx/SnO2 QDs/ITO bio-electrode reveal higher sensitivity (0.5148 mu A/mu M cm(2)), lower K-m value (0.022 mu M), faster response time (10 s), and wide linear range of 1-400 mu M with regression coefficient as 0.999, higher charge transfer rate constant 1.63 s(-1).
