A device for wound care, comprising:
- a base layer;
- a functional layer supported on the base layer and containing at least one chemical substance suitable for wound care;
- and
- a coating film laid over said functional layer and having a skin-contact surface,
- wherein said coating film is configured, upon being brought into contact with skin, via the skin-contact surface, to dissolve and to release said chemical substance to skin through the skin-contact surface, and
- wherein the coating film is an atomic layer deposition (ALD) film.
A method for manufacturing a wound care device, comprising:
- obtaining a base layer and applying a functional layer containing at least one chemical substance suitable for wound care onto said base layer,
- depositing, by atomic layer deposition (ALD), a coating film with a skin-contact surface over said functional layer such, that upon bringing said coating film into contact with skin, via the skin-contact surface, the coating film dissolves and releases said chemical substance to skin through the skin-contact surface.
