▎ 摘　　要

NOVELTY - The structure has an electronic gel layer (3), a graphene periodic circular ring array layer (2) and a dielectric protective layer (1) arranged in sequence. The electronic gel layer is provided with a gate region. The gate region is provided with a metal gate (4). The graphene periodic circular ring array layer includes multiple groups of graphene circular ring units arranged in sequence. Each group of graphene ring units includes a third circular ring, a second circular ring and a first circular ring (21) arranged in sequence. The diameter of the outer ring increases successively. The inner diameters of the first circular ring, the second circular ring and the third circular ring are the same. The material of the electronic gel layer is silicon dioxide. USE - Graphene super-surface structure for particle transfer and sorting for used in ultra-surface optical tweezers for use in fields of biology and medicine. ADVANTAGE - The structure is insensitive to the excitation light polarization, only needs to set the time sequence of the external voltage in the operation, so as to realize the switching of the hot spot and transmission of the particles, makes no dependency on the polarization direction of the light source, is simple operation, reduces the complexity of the ultra-surface optical tweezers application, and has no dependency of light source polarization direction. DESCRIPTION OF DRAWING(S) - The drawing shows an ultra-surface structure schematic diagram of a graphene super-surface structure for particle transfer and sorting. 1Dielectric protective layer 2Graphene periodic circular ring array layer 3Electronic gel layer 4Metal gate 21First circular ring 22Second circular ring 23Third circular ring
