Abstract
The present invention relates to a biocompatible membrane, specifically to a minimally swellable biocompatible membrane and the preparation method thereof. The preparation method of the minimally swellable biocompatible membrane comprises the following steps: synthesis of a copolymer containing a skeleton and a hydrophilic group, the introduction of a biocompatible property, the preparation of a biocompatible membrane solution, and the coating of the biocompatible membrane. The present invention can effectively regulate glucose, and has high biocompatibility (long service life) as well, thereby improving the sensitivity, accuracy, reproducibility, stability, specificity and anti-interference ability in a continuous glucose monitoring (CGM) system, prolonging the life time of the CGM, and greatly reducing the cost of the CGM.
