Description

technical field [0001] The invention relates to a dual-channel structured light illumination super-resolution imaging method and device. Background technique [0002] Lipid rafts play an important role in signal transduction on the plasma membrane, and it is of great significance to directly observe the microstructure of lipid rafts and their corresponding cellular functions by using fluorescence microscopy. Lipid rafts cannot be detected due to the diffraction-limited resolution of conventional fluorescence microscopy. Some super-resolution imaging techniques developed in recent years, such as stimulated radiation depletion microscopy (STED) and photoactivated localization microscopy (PALM), have also recently been used in the study of lipid rafts. However, they have only been used for Probes clusters of lipid rafts without being able to detect the physical environment surrounding the rafts. Some recently developed environment-sensitive probes can reflect the physical env...
