Vitamin metal-organic framework-laden microfibers from microfluidics for wound healing

Vitamin MOF-laden microfibers with alginate shells and copper- or zinc-vitamin framework cores are controllably generated by using a coaxial capillary microfluidic spinning approach. The practical value of these MOF-laden hydrogel microfibers in improving tissue wound healing has also been explored based on the antibiosis and antioxidation of the controllably released vitamins, copper ions and zinc ions of the compound materials.
