Poly Ethylene Glycol (PEG)‐Based Hydrogels for Drug Delivery in Cancer Therapy: A Comprehensive Review (Adv. Healthcare Mater. 18/2023)

Drug Delivery Systems The systematic review in article 2300105 by Behnam Akhavan and co‐workers examines poly ethylene glycol (PEG)‐based hydrogels for cancer drug delivery, emphasizing the design criteria for on‐demand drug release in response to stimuli. The article sheds light on the important design factors governing the controlled release of anti‐cancer drugs from PEG hydrogels, considering various stimuli. The commercial viability of these hydrogels and critical limitations that need to be addressed for their successful clinical translation are discussed.
