提出了一种由亚波长硅粒子组成的全介质超表面，在硅粒子中引入适当的缺陷从而破坏结构的对称性，进而使超表面能够激发出陷波模态.将石墨烯与全介质超表面相结合进行DNA和RNA等核酸物质传感检测，对比透射光谱中的谐振模式，发现所设计的超表面能够灵敏的感知周围环境的微弱变化，其在传感检测时的灵敏度可以达到173 nm/RIU，相应的品质因数可达14 416 RIU^-1，具有优异的生物传感性能.全介质超表面是实现超灵敏生物传感检测的一种有效的途径.

It has proposed an all-dielectric metasurface consisting of subwavelength particles, which supports "trapped" mode after the introduction of properly symmetry-breaking in the silicon meta-atoms. Combining the monolayer graphene with all-dielectric metasurface that enables to detect nucleic acids such as DNA and RNA. it has been found that the proposed metasurface is ultra-sensitive to the surrounding environment, its sensitivity in sensing detection can be up to 173 nm/RIU, with the corresponding quality factor of 14 416 RIU^-1, which exhibits excellent biosensing performance by comparing the resonant state in the transmission spectrum. It indicates all-dielectric metasurfaces could be a promising way and platform to realize ultra-sensitive bio-sensors.
