Abstract
A diabetic foot ulcer (DFU) is an open sore or wound that typically develops on the bottom of the foot. Almost 15% of people with diabetes are suffering from delayed wound healing worldwide. The main vehicle for the development of ulcers in the diabetic population is poor circulation and peripheral neuropathy. Chronic injuries from diabetes frequently lead to traumatic lower leg amputations. Hydrogels are three-dimensional gels that can be fabricated from natural polymers and synthetic polymers. Biopolymers are flexible, elastic, or fibrous materials that come from a natural source, such as plants, animals, bacteria, or other living things. Some of the naturally occurring polymers that are frequently employed in wound dressing applications include polysaccharides and proteins. These polymers can be employed for many therapeutic applications because of their inherent biocompatibility, low immunogenicity, non-toxicity, and biodegradability. They represent a tuneable platform for enhancing skin healing. Therefore, this review paper interprets how natural biopolymers and their various hydrogel forms can be potentially used for diabetic wound healing.
