Stable and reusable silver nanoparticle SERS platform for pretreatment-free screening of trace malachite green in environmental water.
The rapid and sensitive detection of malachite green (MG) is critical for environmental safety due to its potential carcinogenicity and strict prohibition in aquaculture. However, practical surface-enhanced Raman scattering (SERS) monitoring is often hindered by the high cost, single-use nature, and matrix-induced degr...
