Plasmonic tweezers are advanced tools that utilize the principles of plasmonics to manipulate nanoscale particles with high precision. They leverage the interaction between light and metallic nanostructures to create highly localized electromagnetic fields, which can trap and move small objects such as nanoparticles, biomolecules, and even single atoms. This technology is especially significant in the field of nanotechnology due to its ability to handle materials at a scale where traditional mechanical tools fail.
