Abstract
The present disclosure relates to a dermal drug delivery platform comprising: a primary wound dressing comprising three-dimensional polymer protuberances that extend upward from the dressing surface to engage the wound. The protuberances comprise at least one biocompatible and/or biodegradable polymer and medicinal nanoparticles. In one embodiment, the medicinal nanoparticles may be metallic and provide surface-area-enhanced galvanic action to drive medicinal ions into the wound bed. Various methods of making the disclosed dermal drug delivery platform, as well as three-dimensional methods of treating a wound using the platform are also disclosed.

An enhanced, wound care system comprising:
- one or more secondary dressing layers juxtaposed between a primary dressing surface and an outer cover;
- wherein the primary dressing surface comprises biocompatible and/or biodegradable polymer protuberances formed thereupon and arranged into certain preferred geometrical patterns;
- wherein each of said polymer protuberances further comprises medicinal nanoparticles embedded therein or thereupon;
- wherein, when said polymer protuberances are brought into contact with a wound, said medicinal nanoparticles are controllably released for purposes of accelerated healing of the wound;
- and
- wherein polymer protuberances with or without embedded medicinal nanoparticles are coated with a medicinal layer.
