Gold nanoparticle SERS substrates from Nikalyte can amplify Raman signals by upto 1000 times compared to standard Raman techniques, for a wide range of analytes. The substrate is simple to use and is therefore suitable for on-site and laboratory purposes to detect trace molecular species in forensics, narcotics, life sciences and food safety.
Nikalyte SERS substrates are made of ultra-pure gold nanoparticles synthesized in vacuum, thus ensuring the high reliability and sensitivity often only associated with costly micropatterned SERS substrates but without the high price tag.
Chemical-free substrate production keeps the nanoparticle surface free of ligands or hydrocarbons. This enables the Nikalyte nanoparticle SERS substrates to exhibit a high Raman signal-to-noise ratio, which is crucial for distinguishing between similar molecules.
Nikalyte SERS substrates find use in pollution monitoring, narcotics, forensics, pharmaceuticals, biosensors and food safety.
