Jiangsu Baisaifei Biotechnology

Jiangsu Baisaifei Biotechnology Co., Ltd. (Biosurf) operates as a specialized technology service provider for the entire industrial chain of medical biological functional coatings. The company was established in Suzhou Industrial Park on February 17, 2017. Its founder, Chen Hong, is a professor at Suzhou University who identified a critical gap in the domestic market, where high-end medical device coatings were monopolized by foreign manufacturers. With over two decades of foundational research in the bio-material surface interface field, Chen Hong's academic background includes a Ph.D. from Nanjing University and postdoctoral research at McMaster University in Canada, which led to the establishment of the Macromolecule and Bio-Interface Key Laboratory at Suzhou University. This deep expertise spurred the creation of Biosurf to pioneer the domestic production of these vital components.

Biosurf delivers comprehensive solutions that encompass coating liquids, coating equipment, application processes, and quality control instruments. The company's business model is centered on providing these integrated services to medical device companies, enabling them to upgrade existing products and launch new ones. Its product portfolio includes a variety of advanced functional coatings such as super-lubricious, anti-coagulant, anti-microbial, and stain-resistant coatings, which are applicable to a wide range of medical devices. Beyond materials, the company also manufactures automated coating equipment and precision testing instruments to ensure consistent quality and performance. Revenue is generated through the sale of these products and by offering a suite of services including coating research and development, ODM production, and comprehensive testing and regulatory support.

The company has demonstrated significant growth and market recognition, securing multiple rounds of financing. Noteworthy funding rounds include a Series B of over 100 million RMB in April 2022, a Series B+ of several tens of millions of RMB in August 2022, and a C round in July 2025. These investments are fueling the expansion of its R&D capabilities, the construction of new production facilities, and its global market penetration. A key achievement for Biosurf was its role as a primary drafting unit for China's first industry standard for vascular device coatings, officially released in February 2024. The company has served over 500 clients, possesses more than 200 patents, and has expanded its facilities to over 22,000 square meters.
