In surface functionalization of a surface with nano- or microparticles, a process is for functionalizing a surface of a solid support with nano- or microparticles. Polymers include polymerized amine-functionalized monomer units. The polymers are used to functionalize a solid support with nano- or microparticles. The resulting nano- or microparticles functionalized polymers includes polymerized amine-functionalized monomer units.

Non-sensitizing pressure sensitive adhesives which are useful in medical applications and other uses where an adhesive is in contact with skin are obtained by energy-curing compositions containing one or more acrylate-functionalized compounds and possibly other components which are selected such that the cured adhesive passes an in vitro cytotoxicity test in accordance with ISO 10993-5 (2009).
