Two-color STED microscopy in living cells
This study demonstrates the first two-color Stimulated Emission Depletion (STED) microscopy in living cells. This breakthrough enables visualization of dynamic nanoscale interactions previously unseen with conventional methods.
Area of Science:
- Cellular biology
- Microscopy
- Biophysics
Background:
- Stimulated Emission Depletion (STED) microscopy offers diffraction-unlimited resolution for imaging cellular processes.
- Conventional microscopy limits the visualization of dynamic nanoscale interactions in living cells.
- Multicolor live cell STED microscopy and suitable labeling technologies have been lacking.
Purpose of the Study:
- To demonstrate the first two-color STED imaging in living cells.
- To overcome limitations in visualizing dynamic nanoscale interactions.
- To develop and apply improved labeling technologies for multicolor STED microscopy.
Main Methods:
- Utilized improved SNAP(f) and CLIP(f) labeling technologies.
- Applied two-color STED imaging in living cells.
- Performed sequential scanning for multicolor imaging.
Main Results:
- Achieved the first realization of two-color STED imaging in living cells.
- Successfully labeled epidermal growth factor (EGF) and EGF receptor (EGFR).
- Reported resolutions of 78 nm and 82 nm for 22 sequential scans.
Conclusions:
- This work establishes multicolor live cell STED microscopy.
- Enables the study of dynamic nanoscale interactions at high resolution.
- Advances live cell imaging capabilities for cellular process visualization.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
