Chapter 8 - Targeting aspects of hydrogels in drug delivery

Abstract

Hydrogels are fascinating three-dimensional soft matrix having biopolymers in and as their backbone. Because of its flexibility, biocompatibility, soft tissue-like morphology, easy to synthesize approach, and sensitivity, this material is widely used as macro- and nanoparticles, slabs, sheets, films, coatings, etc. in numerous biomedical applications such as tissue engineering, regenerative medicine, scaffolds, and drug delivery applications. Sensitivity toward various physiological stimuli such as pH, temperature, electrolytic conditions, light, and ultrasonic radiations has made these materials the first choice in drug delivery applications.
