Sano Diagnostics

Sano Diagnostics is a private U.S. medtech company developing low-cost, disposable point-of-care diagnostic devices for early detection of inflammation-related biomarkers. Its core technology uses gelatin-coated metallic colloidal suspensions that change color in the presence of proteases, enabling rapid visual and quantitative readouts from bodily fluids. The company’s lead focus appears to be chronic wound care, where it aims to measure wound biochemistry to personalize treatment and improve healing outcomes, while the broader platform has been described for osteoarthritis, cancer, gum disease, ocular rosacea, and veterinary applications. Sano Diagnostics appears to be an early-stage platform diagnostics company rather than a therapeutics developer, with prototypes and patent-backed assay chemistry but no evidence of commercialized products or advanced regulatory-stage programs.
