| Summary: | <b>Background:</b> Wound healing in diabetic individuals is a prolonged process, often complicated by infections and impaired tissue regeneration. Innovative strategies combining natural bioactive compounds are needed to enhance repair. <b>Methods:</b> This study reports the development and characterization of natural latex-based biomembranes (NLBs) incorporated with liposome-encapsulated curcumin and papain. The therapeutic efficacy of these composite dressings, in combination with red light-emitting diode (LED) phototherapy, was evaluated in a diabetic rat model. NLBs were produced by blending natural latex with multilamellar liposomes containing either curcumin, papain, or both. In vivo wound healing was assessed by applying the biomembranes to the dorsal lesions and administering red LED irradiation (650 ± 20 nm, 10 min every 48 h) over 11 days. <b>Results:</b> Fourier transform infrared spectroscopy (FTIR) confirmed that the integration of liposomes did not induce significant chemical alterations to the latex matrix. The treated diabetic rats exhibited enhanced wound contraction, with the curcumin and papain groups demonstrating up to 99% and 95% healing, respectively. Plasma fructosamine levels were significantly reduced (<i>p</i> < 0.05), indicating improved glycemic control. <b>Conclusions:</b> Combining NLBs with bioactive-loaded liposomes and phototherapy accelerated wound healing in diabetic rats. This multifunctional platform shows promise for the treatment of chronic wounds in diabetic patients. |
