| abstract |
Adhesive articles containing microtopography, such as microprotrusions, and a coating of adhesive glue, such an adhesive having known toxicity and/or tissue reactive functional groups are described herein. The articles described herein contain a substrate, a plurality of micro features, and an adhesive, such as an adhesive glue. The articles described herein exhibit a 90° pull off adhesion of at least about 1.5 N/cm2. The articles described herein can contain less adhesive than when the adhesive is used alone without microtopography and yet exhibit equivalent adhesive strength with little or no toxicity or other adverse side effects (e.g., exothermic reaction). |
