Results indicated that spherical beads were successfully developed, with encapsulation efficiency ranging from 65.1% to 95.5%, drug loading between 32.5% and 49.9%, bead sizes of 0.75 mm to 0.92 mm, and degrees of swelling from 0.92 to 1.82.

This review systematically analyzes the efficacy of hydrogel- and non-hydrogel-based dressings in acute and sub-acute burn care. Hydrogels with a water content of more than 90% present an environment for healing by way of autolytic debridement, angiogenesis, fibroblast proliferation, and pain relief-they are extremely helpful in partial-thickness burns owing to their cooling and non-adherence characteristics. Additionally, hydrogels can deliver bioactive agents (e.g. antimicrobials) and manage moderate exudate, enhancing their utility in infected wounds. In contrast, non-hydrogel dressings-including foam, nanofiber, and film-based systems-are tailored for heavily exudative or deep burns (e.g. full-thickness injuries). Foam dressings combine high absorbency with mechanical protection, while electrospun nanofibers mimic the extracellular matrix to accelerate cell migration. Key determinants for polymer selection include hydrophilicity, adhesion properties, wound depth, exudate volume, and microbial load. Natural polymers like chitosan and alginate enhance biocompatibility and antimicrobial activity, whereas synthetic variants (e.g. polyurethane) provide mechanical stability. Composite systems integrate these advantages but face scalability limitations. Emerging innovations, such as pH-responsive and sensor-integrated smart dressings, alongside biomimetic designs, promise advancements in personalized burn care.
