VSPARTICLE has developed a nanoparticle print technology to produce nanostructured noble metal layers by depositing nanoparticles produced by spark-discharge. The process works at ambient temperature and rough vacuum (0.2 mbar) without the use of any chemical precursors. The thickness of the deposited layer can range from sparse distribution of agglomerates to multiple microns. The sensing capabilities of the printed nanoparticles and the nano-porous morphology of the printed layers have proven to be very effective for developing SERS substrates that can be used as a standard tool for chemical analysis. This led to the development of Enhansers, a nanotechnology company solely focussed on the production and distribution of nanostructured SERS substrates on a commercial scale. At the same time, the versatile technology that is used for the production of nanoparticles is integrated in the fabrication process. Therefore the customer can quickly print new substrates with different material combinations and morphology, without the need to directly handle nanoparticles. This flexibility allows the fabrication of SERS substrates with different structures and material combinations, thus enabling researchers to use this technology for their fundamental SERS research.
