摘要:
The present application provides articles (10) having a polymeric substrate (12) with a plurality of solid and/or hollow microneedles (20) extending therefrom. Each solid microneedle is formed by a molding process and the microneedle has body with first (30) and second cavities (40) extending therein. The hollow microneedles are formed by removing a portion of the polymeric material disposed between the first cavity and the second cavity. A method for determining the location of a microneedle in an article comprising solid microneedles is also provided. The method comprises directing electromagnetic radiation toward an article comprising a plurality of microneedles and imaging the article.
