Nano-particle enhancement of diagnosis with Laser-Induced plasma spectroscopy

Abstract

This work discusses nano-particle augmentation of signals in laser-induced plasma spectroscopy. Radiation from a Nd: YAG laser device generates optical breakdown at nano-structured target materials. Extensive scientific investigations of different types of nanomaterial explore dependencies on nanoparticle size, laser wavelength and fluence, and time delay to obtain stronger signals from nano-material than from corresponding solid bulk matter. Modelling of the measurements interprets the occurrence of enhanced detectability of atomic species. Opportunities present themselves for biological and spectrochemical synthesis.
