NANOSentinel is developing the world’s only portable technology to detect toxic metal nanomaterials from workplace surfaces in the manufacturing industry. We find the metal contamination you can’t see so your workers won’t get sick. Our easy-to-use surface test will quickly identify and quantify contamination to prevent exposure to nanomaterials, protecting workers’ health.


Reduces costs associated with workplace time-loss due to injuries and compensation claims.


Protects workers’ health, reduces risk of cross-contamination, unintentional, and prolonged exposure to toxic nanomaterials.


Easy-to-use, on-site detection enables timely risk assessment.
