Poly-dispersed 50 – 200 nm nanospheres are citrate-capped for extended stability. Each batch is fully tested and validated for SERS performance as part of the production process.
Nanoparticles offer high performance in an easy-to-use format.
The sample can simply be mixed with colloidal solution before measurement. A salt solution is often added to induce nanoparticle aggregation and generate SERS hotspots.
EXAMPLE APPLICATIONS:
Narcotics Detection -Identification of trace drugs in complex mixtures
Food & Beverages -Authentication of foodstuffs including honey, olive oil, and saffron
Pesticide Detection -Detection of trace agricultural chemicals, pesticides, insecticides, and herbicides
