Abstract
One or more embodiments include antimicrobial bandages with nanostructures, formation thereof, and usage thereof to facilitate wound healing. In one embodiment, a bandage apparatus that facilitates healing a wound is provided. The bandage apparatus includes a substrate having an attachment mechanism that facilitates removably attaching the substrate to a part of a body having the wound. The bandage apparatus also includes a nanostructure film provided on a surface of the substrate and configured to contact the wound when the substrate is attached to the part of the body having the wound, wherein the nanostructure film includes a plurality of nanostructures.
Claims3
An antimicrobial bandage, comprising:
- a substrate;
- nanospikes provided on a first surface of the substrate;
- and
- an adhesive layer formed on the first surface of the substrate and formed around the nanospikes, wherein the first surface of the substrate is configured to contact the wound when the substrate is attached to the part of the body comprising the wound, wherein the nanospikes have a structure that is configured to facilitate an increase in bacterial growth associated with the wound to improve the likelihood of puncturing the bacterial growth with the nanospikes, wherein the structure of the nanospikes to facilitate the increase in the bacterial growth comprises a combination of:
- a first diameter of a distal end of a nanospike of the nanospikes being between 1 nanometer and 200 nanometers;
- a second diameter of a proximal end of the nanospike of the nanospikes being between 1 nanometer and 1000 nanometers;
- a height of the nanospike of the nanospikes being between 100 nanometers and 10000 nanometers;
- and
- a pitch between the nanospike and a second nanospike being between 100 nanometers and about 2000 nanometers, thereby facilitating healing of the wound, and wherein the adhesive layer facilitates removably attaching the antimicrobial bandage to the surface of the body comprising a wound.
