of adhesive tape creates radicals on the tape’s
surface. These radicals are capable of reducing metal salts to the
corresponding metal nanoparticles. In this way, the mechanically activated
tape can be decorated with various types of nanoparticles, including
Au, Ag, Pd, or Cu. While retaining their mechanical properties and
remaining “sticky,” the tapes can exhibit new properties
derived from the presence of metal nanoparticles (e.g., bacteriostaticity,
increased electrical conductivity). They can also be patterned with
nanoparticles only at selective locations of mechanical activation.
