Microplasma-assisted green synthesis of glucose-stabilized silver nanoparticles: a dual-functional platform for SERS detection and synergistic reduction of binary dyes.

ABSTRACT: A rapid and environmentally sustainable approach for synthesizing glucose-stabilized silver nanoparticles (G-AgNPs) was developed using an atmospheric-pressure microplasma process that completely eliminates the need for conventional chemical reductants and surfactants. The synergistic interaction between plasma-generated reactive species and glucose molecules enabled the one-step formation of uniformly dispersed AgNPs exhibiting dual morphologies-spherical (∼8 nm) and hexagonal (∼16 nm)-with distinct localized surface plasmon resonances (LSPR) centered at ∼403 nm. These nanostructures produced abundant electromagnetic "hot spots," functioning as highly sensitive and reproducible SERS substrates capable of detecting Rhodamine 6G at concentrations as low as 10^-9 M (enhancement fac
