A simple method using LC/MS/MS was developed and validated to determine residues of MG and leucomalachite LMG in fish fillet. A modified QuEChERS Quick, Easy, Cheap, Effective, Rugged, and Safe technique was used to perform the sample preparation. The optimal …read more
This study established a novel surface‐enhanced Raman spectroscopy method coupled with simplified protocol and nanorod substrates to detect banned substances and crystal violet in fish samples. SERS is a rapid and accurate method that can be used to …read more
· A specific and sensitive colorimetric aptasensor is described for the determination of MG. It is exploiting the inhibition of the peroxidase-like activity of nanoparticles AuNPs. The AuNPs act as enzyme mimics that catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine TMB by H2O2 to yield a dark blue solution. The catalytic activity is inhibited by hexadecyl ...read more
The key parameters influencing efficiency were investigated, such as the type of ionic liquids, the volume of ionic liquid, time, and so on. Under the optimum conditions, good reproducibility of the performance was obtained RSD, 1.0% for MG and 5.9% for CV, n = 5.read more
