Green synthesis of silver nanoparticles from corn cob aqueous extract for colorimetric cysteine detection in serum simulated with cysteine samples

In this study described a green approach for synthesizing silver nanoparticles (AgNPs) with corncob acting as reducing and stabilizing agent to rapidly detect of L-Cysteine (Cys). To obtain an appropriate condition AgNPs variations in the reactant such concentration, pH, processing speed were altered. The synthesized AgNPs, that have sizes 50–100 nm capped by extract (CCB), became virtually hexagonal re-dispersed well aqueous solution. explored their possible structural characterization. Significantly, CCB/AgNPs combination demonstrated very high sensitivity Cys detection 30 nM limit (LOD) selective among 12 amino acids. Furthermore, was applied human serum error rate less than 5%. As result work, rapid employing green-synthesized developed.
