Title: Weiqing Sun: Innovator in Hyaluronic Acid Gel Technology
Introduction
Weiqing Sun is a notable inventor based in Zhejiang, China, recognized for his contributions to the field of polymer materials, particularly in the development of cross-linked hyaluronic acid gels. With a total of four patents to his name, he has made significant strides in enhancing the properties and applications of hyaluronic acid in medical and pharmaceutical fields.
Latest Patents
Weiqing Sun's latest patents include a preparation method for cross-linked sodium hyaluronate gel. This innovative method involves creating an alkaline aqueous solution of hyaluronic acid and formulating a sodium hyaluronate alkali liquor with a concentration of 10-30% g/ml. The cross-linking reaction utilizes divinyl sulfone or 1,4-butanediol diglycidyl ether as a cross-linking agent, conducted at a temperature of 20-40°C for 4-8 hours. The advantages of this method include easily available raw materials, mild reaction conditions, high cross-linking efficiency, and a simple process. The resulting cross-linked sodium hyaluronate exhibits a three-dimensional network structure with excellent mechanical properties, making it suitable for use as a drug carrier and tissue engineering scaffold material.
Another significant patent involves a method for preparing cross-linked hyaluronic acid gel. This method introduces a new disulfide cross-linking agent, N,N-bis(acroloyl)cystamine, which effectively addresses degradation issues associated with cross-linked hyaluronic acid. The controllable disulfide bond ratio enhances the cross-linking modification degree, solving the challenges of degradation in highly cross-linked hyaluronic acid gels. The cross-linked material has promising applications in drug delivery and tissue engineering.
