TRAPPING OF MICRO AND NANO SCALE OBJECTS BASED ON LOCALIZED SURFACE PLASMON

摘要

Methods for optically trapping and manipulating micro- and nano-sized particles by using light to induce localized surface plasmon resonance on metallic surface of a substrate. The method includes the steps of contacting a substrate with a medium having particles suspended therein; focusing a beam of coherent light onto the substrate such that the beam induces surface plasmon resonance; and trapping at least one of the suspended particles using a light induced dielectrophoresis force generated by the surface plasmon resonance.
