We introduce NanoPen, a novel technique for flexible, real-time reconfigurable, and large-scale light-actuated patterning of single or multiple nanoparticles such as metallic spherical nanoparticles, semiconducting and metallic nanowires, and carbon nanotubes.
We present a study of dipole-dipole interaction between silver nanowires trapped using optoelectronic tweezers. Measurement of the maximum repulsion force between nanowires and self-assembly of nanowires to achieve the lowest potential energy configuration are demonstrated.
We present a new optoelectronic tweezers device that produces electric fields parallel to the plane of the device. This device is capable of trapping and transporting p-type silicon nanowires at velocities of 20 mum/s.
We demonstrate, for the first time, the trapping and manipulation of individual Si nanowires by light-induced dielectrophoresis, or optoelectronic tweezers (OET). Trapping of single Si nanowires, with a diameter of 100 nm and length of 15 mum, is reported using OET with an optical power density of 100 W/cm2 . We show that OET can separate two adjacent Si nanowires and transport a single nanowire at...
