Abstract
We report on trapping of single and multiple spherical gold nanoparticles with 60 to 250 nm diameters using optoelectronic tweezers (OET). Thanks to the low optical intensities required for stable trapping (20 μW over 1.7 μm spot), we estimate the temperature increase in OET-trapped nanoparticles due to absorption to be ΔT ≪ 0.1°C, making OET-trapped nanoparticles suitable for biological imaging and sensing applications. In addition, we observe translational velocities of 68 μm/s and demonstrate trapping of both single and multiple nanoparticles in a single trap.
