Selective voltammetric determination of d-penicillamine in the presence of tryptophan at a modified carbon paste electrode incorporating TiO2 nanoparticles and quinizarine

Simultaneous determination of epinephrine and uric acid at a gold electrode modified by a 2-(2,3-dihydroxy phenyl)-1, 3-dithiane self-assembled monolayer

“…It has been reported that cathecols can be used as modifier in electrocatalysis of neurotransmitters such as EP [25,26] and also, dithianes form good self-assembled monolayers [36]. Thus, in continuation of our recent studies concerning the preparation of modified electrodes [37][38][39][40], in the present work, we report the preparation and application of DPDSAM as a new electrode in the electrocatalytic procedure and the determination of EP in an aqueous buffer solution. The analytical performance of the modified electrode has also been evaluated during EP-quantification in the presence of UA.…”

Simultaneous Determination of Isoproterenol, Acetaminophen and Folic Acid Using a Novel Nanostructure‐Based Electrochemical Sensor

“…Therefore, there is a requirement for the development of these nanoparticles with tuned properties 33. Titanium dioxide nanoparticles (TiO 2 ) nanoparticles have been also revealed to afford good biocompatibility, large surface area, good dispersing properties, and fast electron transfer ability, which had been applied for either mechanistic study or the fabrication of electrochemical sensors for Simultaneous determination of drugs 34–37. The fabrication of electrodes modified with nanoparticles has been the focus of recent attention owing to enhancement of the response signal, increased sensitivity and better reproducibility 35, 38–40.…”

Electrochemical determination of ascorbic acid, uric acid and folic acid using carbon paste electrode modified with novel synthesized ferrocene derivative and core–shell magnetic nanoparticles in aqueous media

“…[21][22][23][24][25][26][27] Nanomaterials and nanosensors are important in this regard, [28][29][30][31][32][33][34][35][36][37] especially core-shell nanomaterials, due to their technological applications in biosensors, [38] removal of microbial biofilms, [39] magnetic drug targeting, [40] controlled drug release, [41] antimicrobial activity [42] or diagnostic methods in medicine.
