摘要：
Microneedle patches have been developed that can be used to deliver therapeutic, prophylactic, diagnostic agents and/or dyes to the skin. The microneedles encapsulate the agent(s) to be delivered. These are formed of a biodegradable polymer that dissolves upon insertion into skin or tissue, so that the microneedles break off from the substrate forming the patch, remaining in the skin/tissue at the site of insertion. The patches are used to create a tattoo or to deliver therapeutic, prophylactic or diagnostic agent in combination with a tattoo. In one embodiment, the microneedle patch contains both vaccine and dye pigments to administer vaccine and record such administration in one application of the microneedle patch.
