摘要

Localized surface plasmon resonance (LSPR) in different metallic nanostructures with sharp field gradient and extremely strong field intensity below the diffraction limit are the keys of near-field optical nano-tweezers for efficiently manipulating tiny bio-object. To further enhance the field gradient and intensity of LSPR and improve accessibility for the target object in nano-tweezers, we propose and realize a plasmonic bowtie notch design with assisted curved grooves for coupling more surface plasmon polariton waves into the LSPR. In experiments, our presented design shows the improved low power consumption for stably trapping bio-sized particles, which is promising for realizing an efficient nano-tweezers.
