Enhanced response induced by polyelectrolyte-functionalized ionic liquid in glucose biosensor based on sol–gel organic–inorganic hybrid material

Carbon nanotube/gold nanoparticles/polyethylenimine-functionalized ionic liquid thin film composites for glucose biosensing

“…Ionic liquids have been extensively used as modifiers recently at electrode surfaces for fabrication of gas sensors (Jin et al, 2006;Yu et al, 2005) and biosensors (Liu et al, 2005a;Yang et al, 2007a) due to their unique electrochemical properties, such as high ionic conductivity and relatively wide electrochemical window. The general method is to immobilize ionic liquid units on the electrode by physically mixing into polymer matrix.…”

Sol–gel processed ionic liquid – hydrophilic carbon nanoparticles multilayer film electrode prepared by layer-by-layer method

“…Scheme of the surface of sol-gel processed ionic liquid -hydrophilic carbon nanoparticles multilayer film electrode prepared by layer-by-layer method. transfer reaction as the irreversible electroreduction of hydrogen peroxide in an acidic solution provides valuable information on the surface effect [17,33,46,[46][47][48]. The voltammetric experiment reveals a significant increase of the faradaic current for electrodes with immobilised CNPs (Fig.…”

“…Less attention was paid to -electrodes modified with RTIL appended films. Cationic imidazolium components -are self assembled on the solid substrate [13,14] or covalently bonded to polymer film [15][16][17][18][19][20]. Electrodes covered by polyelectrolyte functionalised RTIL films can be used in supporting electrolyte free solution [16,18] or applied for electrochemical sensing of biologically important molecules [15].…”

The Effect of Ionic Liquid Covalent Bonding to Sol‐Gel Processed Film on Ion Accumulation and Transfer

“…Such modified electrodes were found to exhibit electrocatalytic properties [18] and are able to accumulate [17,19,23,24] or rectify [17,24] ions. They also exhibit enhanced ion transport [20] and were successfully used for inorganic (Prussian blue) nanoparticles growth from ionic substrates [22]. They also form three dimensional structure together with carbon nanoparticles [25].…”
