One strategy that has gained much attention in the last decades is the understanding and further mimicking of structures and behaviours found in nature, as inspiration to develop materials with additional functionalities. This review presents recent advances in stimuli-responsive gels with emphasis on functional hydrogels and microgels. In this regard, the aim of this article is to review the most recent hydrogels utilized for localized post-surgical drug delivery and their clinical usage in wound healing, cancer treatment, spinal, and periodontal surgeries. In addition, the benefits of various smart and stimuli-responsive hydrogels for on-demand drug release are elaborated upon.

Stimuli responsive hydrogels

The present manuscript is concerned with the classification, method of preparation; application in drug deliveryand FDA approved market products of hydrogels with the patent review on hydrogel composition and its manufacturing process. Collectively, recent breakthroughs in the design of stimuli‐responsive nanocomposite hydrogels improve their potential for operating as advanced systems in different biomedical applications that 2020-12-01 · Especially, the stimuli-responsive hydrogels can sense and perform smart functions in the presence of various stimuli that collectively contribute to the intelligence of the soft machine systems. Furthermore, facile modification of hydrogels with other functional groups/additives/nanofillers substantially expands their functionalities and further broadens the scope of their application. 2021-03-02 · In addition to hydrogels responding to a single stimulus, dual-responsive hydrogels with enhanced gelation restrictions have been developed for drug delivery. Based on copolymerization of NIPAAm, PAA, and butyl acrylate (BA), a polymer with responsiveness to both temperature and pH was fabricated to deliver basic fibroblast growth factors (bFGFs) to infarcted rat myocardium.

Stimuli-responsive hydrogels are a class of materials that undergo a chemical transformation—and subsequent expansion or contraction—under the influence of a specific external stimulus. Keywords: smart hydrogels, stimuli-responsive hydrogels, controlled release, drug delivery systems, anticancer drug delivery systems Introduction The first mention of hydrogels appeared in the literature at the beginning of the 19th century; they have been described as colloidal gels derived from inorganic salts.
