## Abstract

This work provides
a comprehensive analysis of the effects
of plasmonic
materials on self-healing processes, focusing on recent advances,
challenges, and perspectives. We highlight the unique role of plasmonic
nanostructures in facilitating the efficient repair of fractures in
materials. Despite considerable advances in self-healing materials,
there is still great interest in investigating the specific properties
and applications of plasmonic nanostructures. In particular, silver
and gold nanoparticles exhibit remarkable photophysical properties,
attributed to localized surface plasmon resonance, which enables precise
control over self-repair processes. This review addresses the physical
effects, the fundamental role of thermal energy in healing processes,
and the existing challenges, and ultimately outlines future directions
for research in the field.
