A voltammetric biosensor based on ionic liquid/NiO nanoparticle modified carbon paste electrode for the determination of nicotinamide adenine dinucleotide (NADH)

The synthesis and characterization of azocalix[4]arene based chemosensors and investigation of their properties

“…In recent years, the various sensors have been reported for selective and sensitive determination of metals, biomolecules and organic compounds [37][38][39]. The present study is focused on investigating the ionophoric properties of the upper rim functionalized azocalix [4]arene derivatives (4a-f) toward selected metal cations (Na + , K + , Sr 2+ , Ag + , Hg + , Hg 2+ , Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , Cr 3+ , Al 3+ , La 3+ ).…”

Graphene oxide/NiO nanoparticle composite-ionic liquid modified carbon paste electrode for selective sensing of 4-chlorophenol in the presence of nitrite

“…The development and application of modified electrodes and especially modified carbon paste electrodes have received considerable attention in recent years due to their many advantages, such as good anodic widow's potential, easy manufacture, low price, good stability and renewable surface [31][32][33][34][35][36][37]. The incorporation of electroactive materials such as nanomaterials and ionic liquids into a carbon paste electrode is advantageous and has been widely applied in the electroanalytical systems [38][39][40][41][42][43][44][45].…”

Evaluation of ZnO nanoparticle ionic liquid composite as a voltammetric sensing of isoprenaline in the presence of aspirin for liquid phase determination

“…Moreover, due to their considerably high ionic conductivity, broad electrochemical window and fast ion mobility, ionic liquids have also been utilized as electrolyte, binder and solvents in the electrochemical preparations of modified electrodes [21][22][23][24][25]. IL-based electrochemical sensors have also been extensively reported for direct electron transfer of different types of electroactive compounds such as NADH, folic acid, catecholamines, rutin, ascorbic acid and Sudan I [26][27][28][29][30][31]. Results suggested that the use of ILs could increase the sensitivity of electrochemical response and facilitate efficient direct electron transfer of various biological, environmental and pharmaceutical compounds [32][33][34][35].…”
