Summary
Stimuli-responsive microneedles offer a promising approach for treating diabetic wounds by enabling precise drug delivery. Future research should focus on multifunctional microneedles that respond to multiple stimuli for enhanced therapeutic outcomes.
Area of Science:
- Biomedical Engineering
- Materials Science
- Drug Delivery Systems
Background:
- Diabetic wounds, particularly foot ulcers, are challenging to heal due to factors like infection, hyperglycemia, and hypoxia.
- Traditional treatments for diabetic wounds face limitations in drug permeability and duration.
- Stimuli-responsive microneedles (SRMNs) offer controlled transdermal drug delivery for precision medicine.
Purpose of the Study:
- To review the current state of stimuli-responsive microneedles for diabetic wound treatment.
- To discuss the potential of multifunctional microneedles responding to multiple stimuli.
- To clarify the distinction between SRMNs and microenvironment-associated platforms.
Main Methods:
- Literature review of stimuli-responsive microneedle research for diabetic wound therapy.
- Analysis of current single-stimulus-responsive microneedle strategies.
- Discussion of multi-stimuli-responsive microneedle development and translational barriers.
Main Results:
- SRMNs show promise for treating the complex microenvironment of diabetic wounds.
- Current research predominantly focuses on single-stimulus-responsive microneedles.
- Multifunctional microneedles capable of responding to multiple stimuli are underdeveloped.
Conclusions:
- SRMNs represent a promising therapeutic strategy for refractory diabetic wounds.
- Further development of multi-stimuli-responsive microneedles is needed for advanced wound care.
- Key translational challenges include mechanical properties, scalability, cargo stability, and regulatory approval.

Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
