Hydrogel in Cancer Research: Emerging Trends and Therapeutic Potential

Hydrogels, which are three-dimensional hydrophilic polymer networks capable of holding substantial amounts of water, have become a valuable tool in cancer research. Their excellent biocompatibility, adjustable physical characteristics, and capacity to replicate the extracellular matrix (ECM) render them highly suitable for diverse biomedical applications. This manuscript provides a thorough review of the current and emerging roles of hydrogels in cancer research, including tumour modelling, drug delivery, immunotherapy, and tissue engineering. The discussion includes key advancements, current challenges and potential future outlooks to elucidate the potential of hydrogels in transforming cancer diagnosis and treatment.
