Method for manufacturing hyaluronic acid derivatives sponge and hyaluronic acid derivatives manufactured thereby

摘要

The present invention relates to a method for producing a hyaluronic acid derivative and a sponge made of a hyaluronic acid derivative whereby sponge and, more particularly, a cross-linked hyaluronic acid derivative by a freeze- drying method the mechanical strength properties are easily produced in good sponge form by the solid and non-toxic biodegradable hyaluronic acid control ability that can provide excellent hyaluronic acid derivative sponge and relates to a method for producing hyaluronic acid is sponge derivative thereof prepared by the derivative sponge . Hyaluronic acid derivatives are excellent biocompatible sponge of the present invention , biodegradable adjustment function , it has a mechanical strength of dental implants , orthopedic implants , support cells , such as drug delivery system can be used for a variety of purposes . ;
