The laser-triggered dynamical plasmonic optical trapping of targets and advanced Raman detection sensitivity†
Abstract
A novel method involving the laser-triggered Ag-nanoparticle-based plasmonic optical trapping of targets is developed. This dynamically optimized Raman enhanced protocol exhibits superior detection sensitivity for Serratia marcescens and tetrabromobisphenol A, with LOD values of 5 × 105 CFU mL−1 and 6 × 10−7 M, respectively.
