1 Introduction The optical properties of plasmonic nanoparticles have been the subject of extensive research over the past four decades. When illuminated with light of appropriate wavelength, these nanoparticles generate strong electric fields at their surfaces due to localized surface plasmon resonances (LSPR). The LSPR characteristics can be finely tuned by adjusting parameters such as particle size, shape, composition, and the geometric arrangement of interacting or aggregated particles.

Introduction Click to copy section linkSection link copied! The widespread proliferation of plastics has led to an alarming increase in plastic waste, much of which ends up in the oceans. This waste undergoes fragmentation into micro- and nanoplastics, (1) which pose significant environmental and health risks due to their ability to cross physiological barriers and disrupt biological functions. (2−4) Plastic became one of the first sources of ocean pollution from human industrial production.
