Design and application of a sol-gel based fluorescent glucose arrays [Sol-gel tabanli floresans glukoz arrayleri'nin hazirlanmasi ve uygulamalari]

Here we present a new sol-gel based fluorescent glukoz biosensor. The sensor is based on the pH sensitive fluorescent dye entrapped in a tetraethoxysilane (TEOS) based sol-gel together with glukoz oxidase. Micro-analytic sustem which can measure the pH induced chance in the fluorescens intensity due to the enzymatic reaction in spotted layer on the glass surface was used as a measuring system. The system was calibrated to glukoz. As well as characterization, glukoz biosensing in such fruit juice samples were carried out. ©2009 IEEE.
