Abstract
- Development of novel materials for different analytical applications such as optical sensors is one of the major topics of modern scientific research. In this study, a nanosensor based on highly stable silver nanoparticles (AgNPs) conjugated with polystyrene-block-poly(2-vinyl pyridine) [PS-b-P2VP or P(S-VP)] copolymer was synthesized using two-phase one pot protocol. The nanosensor was characterized by UV–vis spectroscopy, zetasizer, FTIR and AFM. Polystyrene-block-poly(2-vinylpyridine)-conjugated silver nanoparticles [P(S-VP)-AgNPs] were further utilized as colorimetric sensor for thiocarbamate pesticide, cartap. P(S-VP)-AgNPs nanosensor allowed for rapid and quantitative detection of cartap in concentration range of 0.036–0.36 μgL−1 with detection limit as low as 0.06 μgL−1. The prepared sensor efficiently detected cartap in presence of other interfering pesticides. P(S-VP)-AgNPs demonstrated great potential for in situ detection of cartap in water and blood plasma.
