Title:
PH RESPONSIVE SELF-HEALING HYDROGELS FORMED BY BORONATE-CATECHOL COMPLEXATION
Document Type and Number:
WIPO Patent Application WO/2012/159106
Kind Code:
A3
Abstract:
Biocompatible hydrogels made from cross-linked catechol-borate ester polymers are disclosed, along with methods of synthesizing and using such hydrogels. The hydrogels of the present invention are prepared by boronic acid-catechol complexation between catechol- containing macromonomers and boronic acid-containing cross-linkers. The resulting hydrogels are pH-responsive and self-healing, and can be used in a number of different biomedical applications, including in surgical implants, in surgical adhesives, and in drug delivery systems is data provides further evidence of the viability of using the disclosed hydrogels for in vivo in biomedical applications.
