△ [18p-E204-11] Assembly Formation of Numerous Nanoparticles by Novel Optical Tweezers Using Semi-Conductor and Metal Substrates with Nano-structured Surfaces
Keywords:optical tweezers, nano-structures, optical manipulation
Recently, we demonstrated a novel optical trapping technique. We named it Nano-Structured Semi-Conductor-Assisted (NASSCA) optical tweezers using nanostructured silicon surfaces. An enhanced optical force would be caused by multiple light scattering around the surfaces without electronic excitation. Such nanostructured surfaces plays an important role for the enhanced optical forces. In the present study, we investigated optical trapping behaviors using nanostructured silicon and titanium substrates.
Using black silicon, numerous polystyrene nanoparticles were simultaneously trapped, resulting in formation of 3-dimensional assembly over the irradiation area. We believe that optical tweezers using a black silicon and a black titanium substrate will become powerful tools for molecular assembly formation.
