Abstract

A scalable strategy for in-situ growth of silver nanoparticles (AgNPs) on flexible polydimethylsiloxane (PDMS) films to construct a highly sensitive AgNPs@PDMS surface-enhanced Raman scattering (SERS) substrate for the determination of malachite green is proposed. The substrate exhibits excellent uniformity and performance, with an enhancement factor of 4.5 × 10⁷ for 4-mercaptobenzoic acid (4-MBA) and a detection limit of 10^− 11 M. Moreover, it can detect malachite green in aquaculture wastewater and on irregular aquatic surfaces. Its strong linear correlation between SERS intensity and logarithmic concentration indicates good quantitative potential. UV-vis spectroscopy and spike-recovery experiments further verify its reliability. The AgNPs@PDMS substrate thus offers a reliable and promising platform for rapid on-site detection of illegal additives in aquaculture.
