In the light of the Electron microscope light source, what we can see is such a world. Electronic staining endoscope light source can help us to observe the tiny virus, cell micro structure, but can only get black and white picture. With special dye labeled samples, electron microscope light source has been obtained by multi color electron microscopy. How can this be done?

Microscope light source also has its own shortcomings: This is a black and white world without color. There are different colors of visible light, we can also easily give the specific composition of biological tissues plus staining or fluorescent labeling. And the image that the electronic staining endoscope light source obtains is to reflect the electronic number of "gray map", in which there is no color information. People can paint the picture of the Microscope light source, but this is not a selective way to highlight the structure to be observed. If the little gray difference in the original image, the Microscope light source late color will be very difficult to separate them.

This time, researchers have brought some new ideas for the image of the electronic staining endoscopic light source. They attached different metal elements to the dye molecules, and let them precipitate to the periphery of the specific marker. Although there is still no real sense of color under the electron microscope light source, these dyes can produce a signal that is 0 different from the energy loss of the projection electron. As a result, it is equivalent to the sample with a different color labels.

In imaging, the researchers project a beam of kinetic energy to the sample. When the electronic staining endoscopic light source the sample, will collide with the atoms, and a part of the energy loss in different places, using Microscope light source dye treatment and the energy loss of the light microscope will produce significant differences. electron microscope light source By testing these differences, you can make the location of the dye stand out from the background.

In the past twenty years, ultra high resolution fluorescence electron microscope light source technology is breaking through the limits of the optical electron microscope, and now, the world has become colorful. The progress of these technologies will lead scientists to electronic staining endoscopic light source better understand the fine structure inside the cell, uncover more micro world life mystery.
