nanotechnology

Thân thiện

A scientist uses nanotechnology to repair a microscopic device.

Definition

1. Noun:
   • The branch of engineering dealing with extremely small things: Nanotechnology is the area of engineering and science focused on creating and using structures, devices, and systems by manipulating matter at the nanoscale, typically dimensions smaller than 100 nanometers (one nanometer is one-billionth of a meter). This often involves controlling individual atoms and molecules.

Usage

• Nanotechnology is used as a singular, uncountable noun to refer to the entire field of study and application.
• It is commonly used in academic, scientific, and technological contexts.

Examples

• Noun:
  • Advances in nanotechnology could lead to more effective drug delivery systems.
  • The university has a dedicated research center for nanotechnology.
  • He is studying nanotechnology to develop new materials.

Advanced Usage

• "The promise of nanotechnology": Refers to the significant potential benefits and future applications expected from this field.
  • Scientists often discuss the promise of nanotechnology in solving complex medical problems.
• "Nanotechnology-enabled": Used as a compound adjective to describe products or devices made possible by nanotechnology.
  • The new sunscreen uses nanotechnology-enabled particles for better protection.

Variants and Related Words

• Nanotech (n): A common informal abbreviation for "nanotechnology."
  • The company is a leader in nanotech.
• Nanoscale (adj/n): Relating to or occurring at a scale of nanometers; the size range involved in nanotechnology.
  • Researchers are working at the nanoscale.
• Nanoparticle (n): A microscopic particle with at least one dimension less than 100 nm, a common subject in nanotechnology.
  • Gold nanoparticles are used in some medical tests.

Synonyms

• Molecular engineering: A closely related term emphasizing the design and construction of molecules for specific purposes.
• Nanoscale science and engineering: A broader, more descriptive term for the field.

Related Phrases

• "Bottom-up approach": A key concept in nanotechnology where materials and devices are built from molecular components which assemble themselves chemically.
  • This new material was created using a bottom-up approach.
• "Top-down approach": Another key concept where nanoscale structures are created by starting with a larger piece and carving it down.
  • Traditional semiconductor fabrication is a top-down approach.
