Super-resolution optical imaging is a consistent research hotspot for promoting studies in nanotechnology and biotechnology due to its capability of overcoming the diffraction limit, which is an intrinsic obstacle in pursuing higher resolution for conventional microscopy techniques. In the past few decades, a great number of techniques in this research domain have been theoretically proposed and experimentally demonstrated. Graphene, a special two-dimensional material, has become the most meritorious candidate and attracted incredible attention in high-resolution imaging domain due to its distinctive properties. In this article, the working principle of graphene-assisted imaging devices is summarized, and recent advances of super-resolution optical imaging based on graphene are reviewed for both near-field and far-field applications.
超分辨率光学成像是推动纳米技术和生物技术研究的一个持续热点，因为它能够克服传统显微镜技术追求更高分辨率的固有障碍——即衍射极限。在过去的几十年中，该研究领域的许多技术已在理论上被提出并在实验中得到验证。石墨烯作为一种特殊的二维材料，由于其独特的性质，已成为高分辨率成像领域最有前途的候选材料，并引起了人们的极大关注。本文总结了基于石墨烯的成像器件的工作原理，并综述了基于石墨烯的近场和远场超分辨率光学成像的最新进展。
