Title: Shape-Forming, Self-Healing, Shear-Thinning and Biadhesive Hydrogels in Biomedical Area.
Abstract: Hydrogels have been extensively used for drug delivery, hemostasis, tissue engineering and regenerative medicine applications. Recently, innovative hydrogels such as shape-forming, self-healing, shear-thinning and bioadhesive hydrogels have been developed and studied for biomedical applications. Based on this we have developed in-situ shape-forming hydrogel for regenerating irregular bone defects  and self-healing hydrogel for treatment of incisional wounds . Further we developed injectable shear-thinning hydrogel for wound healing . In continuation we also developed in-situ bioadhesive hydrogels for bleeding control and preventing sternal infections . In this lecture, fabrication technique, in vitro and in vivo evaluation of the above-mentioned hydrogels and its applications will be discussed in detail.
