Novel microneedle patch accelerates healing of chronic diabetic wounds using light

by

Researchers from Nanjing Drum Tower Hospital, Southeast University, and Wenzhou Medical University have developed a novel microneedle patch that combines MXene hydrogel with nitric oxide (NO) and hypoxia-inducible factor-1α (HIF-1α) plasmid for enhanced diabetic wound treatment. This study, published in the journal Engineering, presents a promising approach to addressing the chronic and non-healing wounds often … Read more

Oxygen-delivering gel heals chronic wounds in mice

by

As aging populations and rising diabetes rates drive an increase in chronic wounds, more patients face the risk of amputations. UC Riverside researchers have developed an oxygen-delivering gel capable of healing injuries that might otherwise progress to limb loss. Injuries that fail to heal for more than a month are considered chronic wounds. They affect … Read more
