“Focused on building systems to
detect materials harmful to humans”

Hi, we’re IdentifySensors. We are a team of scientists, engineers, entrepreneurs and dreamers who are building a platform for nanosensor applications that help optimize resources for a more sustainable future. The platform integrates with the Internet of Things (IoT), producing new types of data and predictive analytics associated with quality, safety and security across business verticals including biologics, food safety & security, infrastructure & environmental monitoring and national security.

We Are IdentifySensors

IdentifySensors is harnessing the diversity of biological systems to power the next generation of low-power biosensors for real-time monitoring of materials harmful to humans. Through its discovery of novel biosensor solutions, the company is enabling the full potential of its platform to detect, monitor and predict how materials can be harmful to humans.
