Sanwa BioTech was established in December 2012 by William Yim and a core team of co-founders with entrepreneurial spirits and cross-functional backgrounds in business, biotechnology, advanced micromachining and microfluidic Lab-On-Chip (LOC) technologies. They formed the basis for this concept of bringing forth a multi-target Point-Of-Care Testing (POCT) solution for faster and more accurate diagnostics of time critical and life threatening diseases. 



At Sanwa BioTech, we believe that impending changes are coming to the way to conventional clinical diagnostic & academic R&D for bio-discoveries. We aim to become a driving force for these changes to revolutionize healthcare solutions into the future. Sanwa BioTech delivers rapid diagnostics and accurate information through our Point-Of-Care Testing (POCT) device and BioChip for faster clinical decisions and better economic outcomes. 

William is the founder of Sanwa BioTech. He has extensive knowledge in electronics, optics, precision mechanics and advanced manufacturing technologies. William is a renowned technologist and inventor, having obtained numerous design and invention awards covering telecommunications, opto-mechatronics and biotechology as well as 80 patents.

We aim to simplify and improve our healthcare and clinical diagnostic outcomes using only a single drop of sample. We focus on combating known and unknown, time critical & life-threatening diseases outbreaks with an automatic, multi-target diagnostics platform with accurate results in 15 minutes.  This rapid and portable Lab-On-Chip platform can be used in human healthcare, pets health, livestock and food safety for disease monitoring, especially at the HAI (Human Animal Interface) to combat infectious diseases outbreaks.


In clinical applications, we develop a wide range of rapid diagnostic panels for testing multiple diseases with a single, simple test, including respiratory infections, cardiac markers, tropical diseases, and sexually transmitted diseases.  


We also develop non-clinical applications for agri-food (animal), and offer customized solutions for clients on pharmaceutical and academic bio-discovery R&D, detection of specific peptide target, be it pathogenic agent or personalized immune-biomarkers.
