Abstract

Nanotechnology has emerged a multidisciplinary technology, feeding to all sectors of nano-sciences and nanoengineering. Smart materials with entirely altered chemical and physical properties and devising new technological methods for producing such materials is the priority of nanotechnology. While working in this direction, recently a new method of atmospheric PLD was explored and developed. This method shifts the fabrication of plasmonic nanomaterials into a completely simple, feasible, environmentally friendly and industrial oriented technique. In this newly introduced method, ablation plume is produced at atmospheric pressure in the interaction of a high-power laser with a target and is captured by the gas to form a nanoparticle (NP) aerosol. The aerosol is transported by adopting various approaches to produce NP film-based SERS substrates for chemical detection.
