Super-resolution fluorescence microscopy techniques have enabled dramatic development in modern biology due to their capability to discern features smaller than the diffraction limit of light. Recently, super-resolution radial fluctuations (SRRF), an analytical approach that is capable of generating super-resolution images easily without the need for specialized hardware or photoswitchable fluorophores, has been presented. While SRRF has only been demonstrated on fluorescence microscopes, in principle, this method can be used to generate super-resolution images on any imaging platforms with intrinsic radial symmetric point spread functions. In this work, we show that SRRF can be utilized to enhance the resolution and quality of transmission electron microscopy (TEM) images. By including an image registration algorithm to correct for sample drift, the SRRF-TEM approach substantially enhances the resolution of TEM images of three different samples acquired with a commercial TEM system. We quantify the resolution improvement in SRRF-TEM and evaluate how SRRF parameters affect the resolution and quality of SRRF-TEM results.
