摘要: In this work, we report the synthesis and fabrication of an enzyme-free sugar sensor based on molecularly imprinted polymer (MIP) surface single walled carbon nanotubes (SWNTs). Electropolymerization 3-aminophenylboronic acid (3-APBA) in presence 10 M d-fructose fluoride at neutral pH conditions resulted formation a self-doped, conducting (MICP) via stable anionic boronic ester complex between poly(aniline acid) d-fructose. Template removal generated binding sites matrix that were complementary to both structure, i.e., shape, size, positioning functional groups, thus enabling sensing with enhanced affinity specificity over non-MIP sensors. Using along MICPs helped develop efficient electrochemical by enhancing analyte recognition signal generation. These sensors could be regenerated used multiple times unlike conventional biosensors which suffer from physical chemical stability.
