Electrochemical Chiral Recognition of Naproxen Using L-Cysteine/Reduced Graphene Oxide Modified Glassy Carbon Electrode
The electrochemical response of S- and R-naproxen enantiomers was investigated on L-cysteine/reduced graphene oxide modified glassy carbon electrode (L-Cys/RGO/GCE). The production of the reduced graphene oxide and L-cysteine on the surface of the glassy carbon electrode was done by using electrochemical processes. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were us...
متن کاملVoltammetric Determination of Chloramphenicol at Electrochemically Pretreated Glassy Carbon Electrode
A sensitive square wave voltammetric method for the determination of chloramphenicol (CAP) was developed using electrochemically pretreated glassy carbon electrode (EPGCE). Electrochemical pretreatment of the electrode greatly enhanced the reduction peak current (Ip) of CAP. The electrochemical investigation of CAP was carried out by using cyclic and square wave voltammetry techniques. CAP show...
متن کاملElectrochemical Detection of Hydrazine Using a Copper oxide Nanoparticle Modified Glassy Carbon Electrode
Metallic copper nanoparticles modified glassy carbon electrode is fabricated by reduction of CuSO4 in the presence of cetyltrimethylammonium bromide (CTAB) through potentiostatic method. As-prepared nanoparticles are characterized by scanning electron microscopy and electrochemical methods. Copper oxide modified glassy carbon electrode (nano-CuO/MGCE) is prepared using consecutive potential sca...
متن کاملElectrochemical Determination of Glycoalkaloids Using a Carbon Nanotubes-Phenylboronic Acid Modified Glassy Carbon Electrode
A versatile strategy for electrochemical determination of glycoalkaloids (GAs) was developed by using a carbon nanotubes-phenylboronic acid (CNTs-PBA) modified glassy carbon electrode. PBA reacts with α-solanine and α-chaconine to form a cyclic ester, which could be utilized to detect GAs. This method allowed GA detection from 1 μM to 28 μM and the detection limit was 0.3 μM. Affinity interacti...
متن کاملElectrochemical studies of tamsulosin hydrochloride using multiwalled carbon nanotube-modified glassy carbon sensor
A differential pulse voltammetric sensor for the determination of tamsulosin hydrochloride (TAM) using multiwalled carbon nanotubes (MWNTs)–Nafion-modified glassy carbon electrode (GCE) has been developed. MWNTs were dispersed in water with the help of Nafion and were used to modify the surface of GCE via solvent evaporation. At MWNT-modified electrode, TAM gave a well-defined oxidation peak at...
