Cytocompatibility, biocompatibility, and biodegradability are amongst the most desirable qualities of wound dressings and can be tuned during the bioplatform fabrication steps to enhance wound healing capabilities. A three-stepped approach (partial-crosslinking, freeze-drying, and pulverisation) was employed in fabricating a particulate, partially crosslinked (PC), and transferulic acid (TFA)-loaded chitosan-alginate (CS-Alg) interpolymer complex (IPC) with enhanced wound healing capabilities. The PC TFA-CS-Alg IPC bioplatform displayed fluid uptake of 3102% in 24 h and a stepwise degradation up to 53.5% in 14 days. The PC TFA-CS-Alg bioplatform was used as a bioactive delivery system with an encapsulation efficiency of 65.6%, bioactive loading of 9.4%, burst release of 58.27%, and a steady release of 1.91% per day. PC TFA-CS-Alg displayed a shift in cytocompatibility from slightly cytotoxic (60–90% cell viability) to nontoxic (> 90% cell viability) over a 72-h period in NIH-3T3 cells. The wound closure and histological evaluations of the lesions indicated better wound healing performance in lesions treated with PC TFA-CS-Alg and PC CS-Alg compared to those treated with the commercial product and the control. Application of the particulate bioplatform on the wound via sprinkles, the in situ hydrogel formation under fluid exposure, and the accelerated wound healing performances of the bioplatforms make it a good candidate for bioactive delivery system and skin tissue regeneration.
