Curran Biotech

Curran Biotech is a private Houston-based nanotechnology and materials manufacturing company developing coatings for HVAC filter media and other porous materials. Its flagship product, Capture Coating, is a patented waterborne nanocoating designed to enhance air filters by imparting superhydrophobicity, breathability, and non-toxicity without compromising airflow or filter ratings. The company positions the technology as a way to reduce airborne transmission risk by capturing liquid-borne contaminants, including virus-laden respiratory droplets, at the filter surface. Curran Biotech originated as a University of Houston spinout and markets its products across building, institutional, and distribution channels in North America and Europe. While it is not a drug-development biotech, it is healthcare-adjacent through indoor air quality and infection-control applications.
