ABSTRACTHydrogels now play a more crucial role than ever thanks to the development of technology. Because of their unique properties, hydrogels can withstand high water and biological fluid concentrations without losing their ability to hold them in their three-dimensional networks. Typically, hydrogels are wet, rubbery, and soft materials. Additionally, they can respond to fluctuations in environmental stimuli. Hydrogels can swell in the solvent or shrink in the state of non-solubility. Moreover, they can even undergo shape volume changes of external stimuli like pH, temperature, light, and electric signals. They are highly regarded as a versatile product and can be used in a variety of medical and industrial settings, including agriculture, the food industry, wound dressing, and implants, because of their hydrophilic structure. In recent years, the development of smart hydrogels that can respond to changes in the environment has been enhanced in a myriad range of applications. This study offers a review of the various ways that hydrogels have been used in two distinct fields, particularly the medical one.
