Gel-Based Drug Delivery Platforms: A Critical, Mechanistic Review of Design, Cross-Linking, and Disease-Specific Translation (2010–2026)
Gel-based novel drug delivery systems (NDDS) occupy a mechanistically distinct niche among controlled-release platforms because they decouple three design variablesnetwork cross-link density, continuous-phase polarity, and stimulus sensitivitythat in particulate carriers (liposomes, polymeric nanoparticles) are often i...
