Changwei System Technology

Changwei System Technology is a Shanghai-based biochip and integrated-circuit design company focused on specialty bio-integrated circuit chips for life science applications. The company has been described as the biochip subsidiary behind chips used in AnPac Bio's cancer screening and detection platform, with products already commercialized and in volume production. Its work appears centered on in vitro diagnostics and medical-device-enabling chips rather than therapeutic drug development. Public disclosures also indicate development activity for a new biochip related to a novel cancer treatment project and a biochip for an automatic drug injection device for diabetes patients. Overall, Changwei appears to be a small, active health-technology company operating at the intersection of semiconductors, diagnostics, and medical devices.
