electron microscopy

Thân thiện

A scientist examines a sample using electron microscopy.

Definition

1. Noun:
   • A technique of microscopy using electron microscopes: Electron microscopy is a scientific method for obtaining high-resolution images of specimens. It uses a beam of electrons, rather than light, to illuminate the sample, allowing for much greater magnification and resolution than is possible with a light microscope.

Usage Examples

• Noun:
  • The detailed structure of the virus was revealed through electron microscopy.
  • Electron microscopy is essential for studying nanomaterials.
  • Researchers used electron microscopy to examine the cellular organelles.

Advanced Usage

• "Cryo-electron microscopy (cryo-EM)": A specific technique where the sample is studied at cryogenic temperatures, often used to determine the 3D structures of biomolecules.

  • Cryo-electron microscopy revolutionized the field of structural biology.

• "Transmission electron microscopy (TEM)": A type where electrons pass through a very thin specimen to form an image.

  • Transmission electron microscopy provides information about the internal structure of cells.

• "Scanning electron microscopy (SEM)": A type where a beam of electrons scans the surface of a sample to create a detailed 3D-like image.

  • Scanning electron microscopy showed the intricate surface texture of the insect's wing.

Variants and Related Words

• Electron microscope (n): The instrument used to perform electron microscopy.

  • The laboratory purchased a new electron microscope.

• Microscopist (n): A scientist who specializes in using microscopes, including electron microscopes.

  • The microscopist prepared the sample for imaging.

Synonyms

• EM (abbreviation): A common abbreviation for electron microscopy.
• Ultramicroscopy: A less common, more technical synonym.

Related Phrases

• "To perform electron microscopy": To carry out the technique.

  • The team will perform electron microscopy on the alloy.

• "Image obtained by electron microscopy": Describing the origin of a micrograph.

  • The image obtained by electron microscopy was stunningly detailed.
