| Abstract: | We have investigated the plasmonic trapping of dielectric nanoparticles by using engineered gold nanoblock pairs with ∼5-nm gaps. Pairs with surface-plasmon resonance peaks at the incident wavelength allow the trapping of 350-nm-diameter nanoparticles with 200 W/cm2 laser intensities, and their plasmon resonance properties and trapping performance are drastically modified by varying the nanoblock size of ∼20%. In addition, plasmon resonance properties of nanoblock pairs strongly depend on the direction of the linear polarization of the incident laser, which determines the trapping performance. |
