METALLIC NANOPARTICLE MANIPULATION USING. OPTOELECTRONIC TWEEZERS. Arash Jamshidi, Hsan-Yin Hsu, Justin K Valley, Aaron T Ohta, Steven Neale, and Ming C. Wu Berkeley Sensor & Actuator Center (BSAC) and Department of Electrical Engineering and Computer Sciences, University of California, Berkeley, California 94720, USA. ABSTRACT (hydrogenated amorphous silicon) is deposited on the We report on trapping of single and multiple bottom ITO substrate. The liquid solution containing the spherical gold nanoparticles with 60 to 250 nm diameters dispersed metallic nanoparticles is sandwiched between using optoelectronic tweezers (OET). Thanks to the low the top ITO electrode and the photoconductor substrate. A. optical intensities required for stable trapping (20 ptW 635-nm diode laser is used to interact with the over ptm spot), we estimate the temperature increase in photoconductive layer and trap the metallic nanoparticles. OET-trapped nanoparticles due to absorption to be AT <. 0C, making OET-trapped nanoparticles suitable for biological imaging and sensing applications.
