The incidence of chronic diabetic wounds is increasing with the growing number of diabetic patients, and conventional wound dressings have proven to be ineffective in treating them. To address this challenge, researchers have developed artificial dermal substitutes using collagen and hyaluronic acid, which are crucial extracellular matrices. However, these subsitiues lack precision and targeted treatment. To overcome this limitation, a gene liposome nanocomplex-loaded dermal substitute (GDS) has been developed as a potential solution. This innovative biomaterial combines the benefits of liposome nanocomplexes with dermal substitutes to offer a more accurate and effective treatment option for chronic diabetic wounds. The GDS has the ability to deliver genes and therapeutic agents specifically to the wound site, promoting angiogenesis and accelerating the wound healing process. Overall, the GDS presents a promising new approach for the clinical treatment of chronic diabetic wounds, offering a targeted and effective solution for this growing problem.
