Abstract

Abstract:

We devise a portable immobilized enzyme biosensor analyzer for the requirement of instant analysis without power supply. It includes a microcontroller STC12C5A32S2 (a main controller) and a highcapacity rechargeable Liion battery (a power supply). We also employ a glucose biosensor and standard glucose solution to test its performance. Test result shows that it has better consistency for the repetition test of the same sample and better linear response for different concentration samples.

Key words: STC microcontroller, biosensor, immobilized enzyme, portable analyzer

CLC Number:
