Biosensors have been prepared by modification of glassy carbon electrodes with functionalised multiwalled carbon nanotubes (MWCNT) dispersed in the room temperature ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethane)sulfonimide (BmimNTF2) and with lipase cross-linked with glutaraldehyde. The biosensor was applied to the determination of olive oil triglycerides by cyclic voltammetry. A phosphate buff...
Carbon film electrodes have been characterised in the room temperature ionic liquids, 1-butyl-3-methylimidazolium bis(trifluoromethane)sulfonimide (BmimNTF2), 1-butyl-1-methylpyrrolidinium bis(trifluoromethane)sulfonimide, (BpyrNTF2) and 1-butyl-3-methylimidazolium nitrate (BmimNO3), by cyclic voltammetry and electrochemical impedance spectroscopy. The electrochemical behaviour of the ionic liquids depended on ...
Two room temperature ionic liquids, 1-butyl-3-methylimidazolium bistriflimide and 1-butyl-3-methylimidazolium nitrate, were employed for enzyme immobilization in a new sol-gel matrix and, for the first time, were successfully applied as electrolyte carriers in a biosensing system. The new sol-gel matrix, based on 3-aminopropyltrimethoxysilane and 1-butyl-3-methylimidazolium bistriflimide mixtures, did not crack...
