Pt-MWCNT modified carbon electrode strip for rapid and quantitative detection of HO in food.

A single-use screen-printed carbon electrode strip was designed and fabricated. Nanohybrids, prepared by deposition of platinum (Pt) nanoparticles on multi-wall carbon nanotube (MWCNT), was modified on the surface of screen-printed carbon electrode for the development of a fast, sensitive and cost-effective hydrogen peroxide (HO) detection amperometric sensor strip. With Pt-MWCNT nanohybrids surface modification, current generated in response to HO by the screen-printed carbon electrode strip was enhanced 100 fold with an applied potential of 300 mV.
