Dry solution to a sticky problem

摘要

Adhesives that stick to skin for long periods of time, or over multiple cycles of use, are vital for medical applications. Such materials have to conform to stringent standards - for example, they must maintain robust adhesion during repeated application and removal without irritating the skin, and be non-toxic. Writing in Advanced Materials, Kwak et al. report an exciting advance towards achieving these standards: an adhesive tape that uses micrometre-scale pillars on its surface to stick to skin. This innovation bypasses the need for a gliie-coated surface, as is commonly used in conventional skin adhesives.
