STED microscopy uses two laser pulses to localize fluorescence at each focal spot. The first pulse is used to excite a fluorophore to its fluorescent state, and the second pulse is a modified beam used to de-excite any fluorophores surrounding the excitation focal spot.

SLM RESEARCH Electrochemistry, imaging with optical (STED) and mass spectrometry (SIMS, NanoSIMS) methods aimed at understanding the chemistry of single nerve cells, single vesicles, neural communication in cell networks and in the Drosophila nervous system; and understanding molecular messengers in cell differentiation. Fig. 1 Correlative imaging. (A) Images of the same area are acquired in different modes.The confocal and STED images are acquired in reflection, while the AFM probe reaches the sample from above, providing a three-dimensional topographical view at high resolution. Due to their small sizes, good stability, and surface functionalization, the cell‐surface markers and subcellular structures are specifically labeled by the AIE dot bioconjugates. Remarkably, stimulated emission depletion imaging with AIE dots is achieved for the first time, and the spatial resolution is significantly enhanced to ≈95 nm. For single color STED imaging, SiR-tubulin or SiR-actin were added to DIV15 neurons in the BrainPhys medium at a final concentration of 1 µM during 1.5 hr at 37°C. For dual color imaging, SiR-tubulin and SiR700-actin were added to to the BrainPhys medium at 1 µM final concentration each and neurons were exposed during 1.5 hr at 37°C.

Stimulated emission depletion microscopy (STED and the related techniques of ground state depletion (GSD and saturated structured illumination (SSIM) are referred to as ensemble focused light imaging techniques, and are based on non-linear optical effects that typically require the application of multiple high-intensity pulsed lasers with specialized modulation filters to control the excitation beam geometry (a technique commonly termed point-spread function engineering). STED microscopy uses two laser pulses to localize fluorescence at each focal spot. The first pulse is used to excite a fluorophore to its fluorescent state, and the second pulse is a modified beam used to de-excite any fluorophores surrounding the excitation focal spot. In this review, we describe how stimulated emission depletion (STED) imaging originally evolved, how it compares to other optical super-resolution imaging techniques, and what advantages it provides compared to previous golden-standards for biological microscopy, such as diffraction-limited optical microscopy and electron microscopy. STED microscopy operates by using two laser beams to illuminate the specimen. An excitation laser pulse (generally created by a multiphoton laser) is closely followed by a doughnut-shaped red-shifted pulse that is termed the STED beam.
