In the realm of scientific research, microscopy has emerged as a transformative tool that enables scientists to delve into the intricate details of biological and medical specimens. However, conventional light microscopy is limited by the diffraction barrier, which restricts the resolution to approximately 200 nanometers. This limitation has hindered scientists from observing and understanding many cellular processes and structures at the molecular level.

Label-free super-resolution microscopy has emerged as a groundbreaking technique that shatters this resolution barrier. It offers a novel approach to imaging biological and medical specimens without the need for fluorescent labels or dyes, which can introduce artifacts and potentially alter cellular functions.

Principles of Label-Free Super-Resolution Microscopy

Structured Illumination Microscopy (SIM)

SIM is a widely used label-free super-resolution imaging technique that utilizes structured light patterns to excite fluorophores within a specimen. By sequentially illuminating the sample with a series of structured light patterns, the emitted fluorescence is collected and processed to create an image with enhanced resolution.

Stimulated Emission Depletion Microscopy (STED)

STED is another powerful label-free super-resolution technique that employs a donut-shaped laser beam to selectively deplete fluorescence from a small region of the specimen. By scanning the donut-shaped beam across the sample, a high-resolution image can be reconstructed by collecting the fluorescence from areas outside the depleted region.

Ground-State Depletion Microscopy (GSD)

GSD is a variation of STED that utilizes a continuous-wave laser beam to deplete the ground-state population of fluorophores, rather than the excited-state population. This approach allows for higher imaging speeds and reduced photodamage to the specimen.
