Abstract

Micro-chips based on organic--inorganic hybrid nanoparticles (NPs) composed of nanoalloys of gold (Au) and silver (Ag) embedded in an amorphous carbonaceous matrix (C--Au--Ag NPs) were prepared directly on a substrate by the laser-induced deposition (for short: LID) method. The C--Au--Ag NPs show a unique plasmon resonance which enhances Raman scattering of analytes, making the \textgreekm-chips suitable to detect ultra-low-volumes (10$-$12 liter) and concentrations (10$-$9 M) of bio-agents and a hazardous compound. These micro-chips constitute a novel, flexible solid-state device that can be used for applications in point-of-care diagnostics, consumer electronics, homeland security and environmental monitoring.
