QUATCARE is an innovative biotechnology company that provides novel, environmentally friendly, antimicrobial materials and disinfection solutions for industrial and human-health applications. 

Our patented technology, QuatCare™, allows antimicrobial activity to be added as a surface coating as well as via direct incorporation into the molecular structure of materials. QuatCare™ efficiently removes a broad range of microbes, including pathogens and microbes problematic to industrial processes.  Our system and applications allow for the prevention of surface colonization and, in some applications, high efficiency microbial removal from water or air.




Founder & CEO

Mario R. Mercado, Jr., earned his BS at Syracuse University and did graduate studies at both Columbia University and New York University.  He has been part of the development team since 2005 in helping to identify particular compounds, develop methods of attachment, and research various fabric and surface integrations, most notably presenting QuatCare's research at the NY Emerging Technologies Summit held at Memorial Sloan Kettering Cancer Center. As a holder of several patents Mr. Mercado has been involved in a number of technology startups as an investor, board member, executive and product developer where interests have included protective polymers for head safety in sports; biosensors for concussion detection; and the integration of gaming with augmented reality technologies. In 2017 he was appointed as Deputy Commissioner of the New York State Athletic Commission by New York State Governor Andrew Cuomo.

Director, Chemical Design & Synthesis

Dr. JaimeLee Iolani Rizzo, Ph.D., is a Professor of Organic Chemistry at Pace University, New York City campus and Assistant Chair to the Department of Chemistry and Physical Sciences and Coordinator for the Professions in Health Advisory Team. Dr. Rizzo's research is focused on the synthesis of novel antimicrobial surfaces based on naturally derived materials. She holds 17 patents and licensing agreements for her work on Antimicrobial Surfaces and Potassium Ion Channels. She has 26 publications in peer-reviewed journals, has presented her work at numerous international and national, and regional conferences, has acquired grants and contracts including those from Johnson & Johnson Wound Management, UK, and The U.S. Army, has worked with over 50 students in her research laboratory, and is the co-author of 2 books: Synthesis of Carbon-Phosphorus Bonds, and Organic Chemistry. In 2017 she was named a Distinguished Fellow by the American Chemical Society and honored at the Award Ceremony in Washington, D.C.


Director, Hydraulics & System Design

Dr. William Blanford, Ph.D., is currently an Assistant Professor of Hydrogeology at Queens College of the City University of New York School of Earth and Environmental Sciences. He earned his doctorate from Arizona State University and is currently a licensed geologist in the State of Texas. Dr. Blanford’s research is focused on the evaluation of processes controlling the fate and transport of microbial and organic chemical pollutants in groundwater and development of remediation methods to address contaminated sites, with specific interests in 1) the determination of the distribution of organic chemicals between environmental phases (e.g. air, water, soil, etc.) and remedial phases (e.g. solubilization agents, sorbents, etc.); 2) the fate and transport of viruses and parasites in groundwater systems; 3) the evaluation of the fate and transport of pathogens and organic pollutants in stream/aquifer systems; and 4) the development of treatment systems for hazardous waste sites and river water. Dr. Blanford has 18 peer-reviewed publications and has presented his work at numerous national meetings and conferences.


Director, Microbiology & Environmental Testing

Dr. O’Mullan is an Associate Professor, serving as the Director and Chairman of the School of Earth and Environmental Sciences, at Queens College of the City University of New York, as well as an Adjunct Associate Research Scientist at the Lamont-Doherty Earth Observatory of Columbia University.  He earned his Doctorate from Princeton University and both an MS and BS at Rutgers University. He has expertise in environmental microbiology, focusing on water quality monitoring, bioaerosol ecology, and aquatic pollution mitigation. He utilizes diverse data collection approaches including microbial cultivation, molecular genetics, geochemistry, and environmental sensors to test experimental hypotheses, characterize environment conditions, and provide solutions to eliminate water and air pollution. Dr. O’Mullan has more than 30 peer reviewed scientific articles, and his research has been funded by foundations and agencies including NSF, US-EPA, Sloan Foundation, Hudson River Foundation and many more.  He has provided testimony on water infrastructure and pollution issues before bodies including the New York State Senate Environmental Committee and New York City Council Committee on Environmental Protection.
