Abstract:
Eco-friendly colorimetric sensors have wide applications in many fields for simple, convenient, and fast detection of various analytes. In this work, a colorimetric sensor based on biogenic synthesized and unmodified silver/silver chloride nanoparticles (Ag@AgCl NPs) was used to simple and fast detection of clindamycin. At this work, aqueous fruit extract of Syzygium cumini was used as a reducing and stabilizing agent without the addition of any other external compound or halide source. The biogenic synthesized nanoparticles were specified using UV-Vis spectroscopy, XRD, and TEM to verify its production, crystallinity and morphology. Then, the ability of the as-prepared Ag@AgCl NPs, without any modifications, was investigated to sense clindamycin in an aqueous medium. The SPR band and color of the solution of Ag@AgCl NPs undergo dramatic changes in exposure to clindamycin. Under the optimized pH, this sensor was shown a linear dynamic range from 10.0 to 100.0 ┬ÁM with good linear relationships (R2= 0.99) for clindamycin. Therefore, the synthesized Ag@AgCl NPs using fruit extract of S. cumini can provide a convenient method of sensing of clindamycin easily.
