By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Enzymes and Coenzymes is the subject of a report. According to news reporting from Tamil Nadu, India, by NewsRx journalists, research stated, "Riboflavin (vitamin B2) immobilized multiwalled carbon nanotubes modified electrode (GCE/MWCNT@RB) has been prepared and demonstrated as a selective and sensitive electrocatalytic flow injection analysis electrochemical sensor for iodate detection. The GCE/MWCNT@RB modified electrode showed a highly stable and well defined surface confined redox peak at an E-1/2 = 155 +/- 20 mV vs. Ag/AgCl with a surface excess value of 4.72 nmol cm(-2)."
The news correspondents obtained a quote from the research from the Vellore Institute of Technology, "Physicochemical and electrochemical characterizations reveal the presence of surface confined riboflavin sites on GCE/MWCNT system. At an applied potential = -0.1 V vs Ag/AgCl, hydrodynamic flow rate = 800 mu L min(-1) and phosphate buffer (pH 2) as a carrier solution condition, the analytical characteristics such as stability, repeatability, linear range and detection limit were described. The relative standard deviation of successive 29 injections of 251 mu M of iodate was 3.61%. Iodate calibration plot was linear in a range of 25-750 mu M with regression coefficient, sensitivity and limit of detection (S/N = 3) of 0.9998, 0.77 mu A mM(-1) and 2.7 mu mol L-1 (9.4 ng/20 mu L) respectively. The new system showed absence of interference with iodide, chloride, nitrate, bromate and perchlorate."
According to the news reporters, the research concluded: "Quantitative detection of iodate in iodized table salts was further demonstrated."
