Stimulated emission depletion (STED) microscopy is a super-resolution imaging technique that overcomes the diffraction limit of light microscopy, enabling the visualization of structures at the nanoscale. Developed by Stefan W. Hell and Jan Wichmann in 1994, STED microscopy uses the selective deactivation of fluorophores to create high-resolution images. With a resolution of up to 20-30 nanometers, STED microscopy has become a powerful tool in various fields, including biology, medicine, and materials science. The technique has been widely adopted, with over 1,000 publications in 2020 alone, and has been recognized with numerous awards, including the Nobel Prize in Chemistry in 2014. As of 2022, STED microscopy has been used in over 500 research institutions worldwide, with applications ranging from cancer research to neuroscience. With its ability to resolve structures at the nanoscale, STED microscopy is poised to continue revolutionizing our understanding of the microscopic world.

Stimulated emission depletion (STED) microscopy has its roots in the early 1990s, when Stefan W. Hell and Jan Wichmann first proposed the concept. However, it was not until 1999 that the technique was first experimentally demonstrated by Hell and Thomas Klar. The development of STED microscopy was influenced by the work of V.A. Okhonin, who patented the STED idea in 1986. Other key figures, such as Eric Betzig and William Moerner, have also contributed to the development of super-resolution microscopy techniques, including photoactivated localization microscopy (PALM) and stochastic optical reconstruction microscopy (STORM)

STED microscopy works by using a combination of excitation and depletion laser beams to selectively deactivate fluorophores, minimizing the area of illumination at the focal point. This process, known as stimulated emission depletion, allows for the creation of super-resolution images with a resolution of up to 20-30 nanometers. The technique is often used in conjunction with other microscopy techniques, such as confocal microscopy and total internal reflection fluorescence (TIRF) microscopy. Companies like Zeiss and Leica Microsystems have developed commercial STED microscopy systems, making the technique more accessible to researchers.

STED microscopy has several key advantages, including its ability to resolve structures at the nanoscale and its compatibility with a wide range of fluorophores. The technique has been used to study a variety of biological systems, including cells, tissues, and organisms. In 2020, researchers used STED microscopy to study the structure of COVID-19 virions, providing new insights into the virus's biology. Other applications of STED microscopy include the study of cancer cells, neurodegenerative diseases, and materials science. The technique has also been used to study the behavior of nanoparticles and biomolecules at the nanoscale.

Several key people and organizations have contributed to the development and application of STED microscopy. Stefan W. Hell, a German physicist, is widely recognized as the founder of STED microscopy and was awarded the Nobel Prize in Chemistry in 2014 for his work. Other notable researchers, such as Thomas Klar and Jan Wichmann, have also made significant contributions to the field. Companies like Ibidi and Abberior Instruments have developed specialized equipment and software for STED microscopy, including STED microscopy software and STED microscopy hardware.

STED microscopy has had a significant impact on the scientific community, enabling researchers to study biological systems at the nanoscale.

As of 2022, STED microscopy continues to be an active area of research, with new developments and applications emerging regularly. Researchers are working to improve the resolution and sensitivity of STED microscopy, as well as to develop new techniques and protocols for its use. The technique is also being used in conjunction with other microscopy techniques, such as single molecule localization microscopy (SMLM) and super-resolution microscopy. Companies like Bruker and HORIBA are developing new equipment and software for STED microscopy, including STED microscopy systems and STED microscopy accessories.

Despite its many advantages, STED microscopy is not without its challenges and limitations. One of the main limitations of the technique is its requirement for specialized equipment and expertise. STED microscopy also requires the use of high-powered lasers, which can be damaging to biological samples. Additionally, the technique can be sensitive to photobleaching and other forms of sample degradation. Researchers are working to address these challenges, including the development of new fluorophores and imaging protocols. For example, Sirius microscopy is a new technique that uses a combination of STED and SMLM to achieve high-resolution imaging with reduced photobleaching.

The future of STED microscopy is likely to be shaped by advances in technology and the development of new techniques and protocols. Researchers are working to improve the resolution and sensitivity of STED microscopy, as well as to develop new applications for its use. The technique is also likely to be used in conjunction with other microscopy techniques, such as correlative light and electron microscopy (CLEM) and cryo-electron microscopy. Companies like Thermo Fisher Scientific and JEOL are developing new equipment and software for STED microscopy, including STED microscopy systems and STED microscopy accessories.

STED microscopy has a wide range of practical applications, including the study of biological systems, materials science, and nanotechnology. The technique is also being used in the development of new medical therapies and treatments, including cancer therapy and gene therapy. Researchers are using STED microscopy to study the behavior of nanoparticles and biomolecules at the nanoscale, which has important implications for the development of new materials and technologies. For example, NanoString Technologies is using STED microscopy to develop new diagnostic tools for cancer research.
