New X-ray microscope for observing intracellular structures
Release date: 2009-01-07
Researchers at the Japan Institute of Physical and Chemical Research published a paper on the online edition of the American Physical Review News published on December 30 last year. They have developed a new type of X-ray microscope that can observe the internal structure of cells. This result is expected. It plays a role in the analysis of the internal structure of proteins and assists in the development of new drugs.
The new microscope uses X-ray coherent scatter imaging to illuminate cells with very regular X-rays, and by detecting subtle changes in the X-ray waveform across the cell, the researchers say. A stereoscopic image of the structure. Researchers at the Institute of Physical and Chemical Research have successfully used this new microscope to successfully observe the internal structure of human chromosomes.
Previously, when researchers were to observe the internal structure of a cell, it was necessary to inject the fluorescent protein as a marker into the cell, and the specimen was also sliced ​​to be suitable for general electron microscope observation. With this new microscope, researchers can observe the inside of the cell without destroying the cell specimen. ——Shanghai Medical Device Industry Association
