Hydrogels represent three-dimensional, interconnected networks known to absorb substantial amounts of H2O but at the same time, being insoluble in the aforementioned solvent. Their exceptional hydrophilic nature, biocompatibility and diverse therapeutic potential position them as highly promising biomaterials within biological and biomedical fields. These materials, on account of their innoxious innate characteristics and safe utilization, have garnered widespread acceptance across tremendous and diverse biomedical applications ranging from traditional therapies to state-of-the-art advancements. This extensive review incorporates a spectrum of varied types of hydrogels, elaborating on both their chemical, physical aspects and also throws light on the rheological, analytical and spectroscopic tools employed for their characterization. It also continues to elaborate on the various mechanisms of gelation for facilitating a better understanding of the topic under discussion. The review also discusses the different strategies which are substantiated in recent times to expand the utilisation of hydrogels. The primary intent of this review is to render a comprehensive understanding of hydrogels as an ideal drug delivery system to undergraduates, graduates, biomedical students and researchers across the globe. It also targets to unravel the fundamental, applied and general aspects of hydrogels, offering valuable insights to help individuals associated with multidisciplinary research and application spheres.
