Our mission is the advancement of molecular physiology and noninvasive health monitoring.

Gaia focuses on saliva diagnostics, development of rapid tests, and detection of proteomic biomarkers. Our primary research centers around the study of HIV/AIDS, hydration monitoring, post-traumatic stress disorder (PTSD), traumatic brain injury (TBI) and post-concussional disorder.

Our Technology

The Gaia technology is powered by two breakthrough innovations that have applications in several diagnostic markets. Saliva handling that increases critical analyte presence and concentration and expanding IP portfolio ensure innovation protection. There is no product on the market to identify mild traumatic brain injuries (mTBI), and Gaia’s technology is ready to meet the growing and currently unmet need. Decentralized, inexpensive testing will revolutionize how brain health is treated and understood.

Our Services

Gaia services include Custom design and development of saliva immunoassays and Clinical and laboratory research of saliva biomarkers for disease diagnostics.
