An electron microscope is a microscope that uses electrons to display the inside or surface of an object. After more than 50 years of development, it has become an indispensable and important tool in modern science and technology. The electron microscope consists of three parts: a lens barrel, a vacuum device and a power cabinet.
The application of electron microscopy technology is based on optical microscopy. The resolution of the optical microscope is 0.2μm, and the resolution of the transmission electron microscope is 0.2nm, which means that the transmission electron microscope is magnified by 1000 times on the basis of the optical microscope.
Electron microscopes can be divided into transmission electron microscopes, scanning electron microscopes, reflection electron microscopes and emission electron microscopes according to their structure and purpose.
Creative Bioarray has many years of experience in electron microscopy services, and can provide customers with technical services for electron microscopy testing of various samples.
Our services including but not limited to:
Transmission electron microscope is often used to observe the fine material structure that cannot be distinguished by ordinary microscope. Transmission electron microscopy is widely used in materials science and biology. The density and thickness of the sample will affect the final imaging quality, and thinner sections must be prepared, usually 50-100nm. Commonly used methods are: ultra-thin section method, frozen ultra-thin section method, freeze-etching method, freeze-fracture method and so on.
Scanning electron microscope is mainly used to observe the morphology of solid surface, and can also be combined with X-ray diffractometer or electron energy spectrometer to form an electronic microprobe for material composition analysis. Samples can be observed under high vacuum, low vacuum, wet conditions and a wide range of low or high temperatures.
Reflection electron microscopes is a combination of imaging, diffraction, and spectroscopy techniques for characterization of topography, crystal structure, and composition of surfaces of single crystals. This technique is applicable to metal, semiconductor, and ceramic surfaces.
Energy dispersive X-ray spectroscopy (EDS) is an analytical method used for elemental analysis and chemical characterization. This method collects the X-rays generated by the X-ray machine or other X-ray sources and the X-rays emitted when the sample interacts for analysis. Since different elements have different emission spectra due to different atomic structures, the element composition in the sample can be determined by analyzing X-ray spectra.
Immunoelectron microscopy combines the ability of antibodies to specifically bind proteins with the high spatial resolution of electron microscopy to determine the location of proteins at the subcellular level.
