▎ 摘　　要

NOVELTY - Electric tuning graphene disk nano-particle plasma optical tweezers comprises conductive adhesive layer 1, disk layer graphene, and substrate layer 3.The substrate layer is paved with the graphene row of the disk. USE - Electrically-tuned graphene disc nano-particle plasma optical tweezers used in biomedicine, micro-sensor and other fields. ADVANTAGE - The tweezers can adjust the chemical potential of the graphene by adding bias voltage, so as to adjust the optical response and the optical force of the particle. The nano particle capture, nano particle measurement and enhanced Raman sensing can be performed effectively. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the electrically-tuned graphene disc nano-particle plasma optical tweezers used in biomedicine.
