چکیده
Based on electric conductivity and wide potential window of ionic liquid (IL) and electric property of single-wall carbon nanotubes (SWCNTs), composite material of IL-SWCNTs was prepared, glucose sensor was built with this material for immobilizing glucose oxidase (GOx). It showed good response, sensitivity and stability for long time for glucose detection. Linear range for the detection of glucose was from 0.5 × 10 M to 12 × 10 M while detection limit was 6.26 × 10 M (S/N = 3).
