“…Szot et al [ 128 ] constructed an electrode based on indium-tin oxide with a controlled amount of conductive nanoparticles by combining the sol containing trimethoxysilyl-functionalized IL (Scheme 8.14 ) and carbon nanoparticles modifi ed with phenyl sulfonate anionic groups. They found that the new electrode could be used as a reversible sponge for Fe(CN) 6 3− anions because of the presence of imidazolium functional groups.…”

Ionic liquids (ILs) have been widely examined as solvents, additives, or catalysts in a variety of applications including organic catalysis [ 1 -5 ], inorganic and materials synthesis [ 6 ], biocatalysis [ 7 -12 ], electrochemistry [ 13 ], pharmaceutical chemistry [ 14 ], polymerization [ 15 , 16 ], and engineering fl uids [ 17 -19 ]. The physicochemical properties of ILs are tunable through a careful selection of a variety of different cations and anions and a rational combination of ion pairs. More interestingly, cations and/or anions can be further functionalized to form so-called task-specifi c ionic liquids (TSILs). The notion of TSILs carrying specifi c functionality tailored for particular applications has proven visionary, and a variety of different functional groups have been grafted onto ILs [ 20 -22 ]. In particular, there is an exponential growth in constructing new TSILs as electrolytes for electrochemical applications. This chapter focuses on a critical discussion of some major types of TSILs and their electrochemical properties and applications. Ether/Thioether-and Hydroxyl/Thiol-Functionalized ILs General Physical PropertiesOur recent review has captured some key physical properties of ether-and alcoholfunctionalized ILs [ 22 ]. The inclusion of alkyloxy or alkyloxyalkyl groups in ILs often lowers the melting points ( T m ) [ 23 -26 ]. Additionally, the lowering of the

“…They are perfectly suited [12] for the LbL technique because of their charged functionalities. This allows for their immobilization on the electrode surface together with positively charged particles such as silicate submicroparticles [13][14][15], gold nanoparticles [16,17], carbon nanoparticles [10,18] or polymers with functional groups bearing positive charge [9,15,19,20]. Some of these electrodes exhibit electrocatalytic properties towards oxidation of biologically important molecules.…”

“…Recently, due to their high electrochemical stability and ionic conductivity, ILs have been intensively adopted in the field of electrochemistry and electroanalysis [17][18][19]. Studies have demonstrated that ILs can be entrapped in conventional matrices, such as chitosan [20,21], cellulose [22], carbon materials [16,23,24], and sol-gel-based silica matrices [25] to construct the biosensor.…”

A novel glucose oxidase (GOD) biosensor was fabricated with a protic ionic liquid (PIL) N-ethylimidazolium trifluoromethanesulfonate ([EIm][TfO]) as the modifier of a carbon electrode. Due to the excellent conductivity and the conformational changes of the microenvironment around the GOD, the electrochemical and biocatalytic properties of GOD immobilized on the PIL-based electrode were dramatically enhanced. A couple of well-defined redox peaks could be observed, with a formal potential of −0.476 V. The GOD biosensor presented good catalytic activity to the oxidation of glucose in oxygen-saturated phosphate buffer solutions. The cathodic peak currents of GOD decreased along with glucose concentrations. A linear response in the range 0.005-2.8 mM was obtained with a detection limit of 2.5 μM. The sensitivity and the apparent Michaelis-Menten constant (K m ) were estimated to be 14.96 μA mM −1 and 1.53 μM, respectively. In addition, the biosensor remained stable over 30 days, indicating its good chemical and mechanical stability. The glucose content of several serum samples was determined by using the newly developed biosensor, and the results were in good agreement with those obtained by hospital measurements. All results suggested that PILs were a good media for supporting biocatalytic processes on the bioelectrode.
