What is the typical size range of nanoparticles?a) 1 to 100 millimetersb) 1 to 100 micrometersc) 1 to 100 nanometersd) 1 to 100 picometers

Typical Size Range of Nanoparticles

Nanoparticles are defined as particles with dimensions in the range of approximately 1 to 100 nanometers. This size range allows nanoparticles to exhibit unique physical and chemical properties that differ significantly from larger bulk materials.

1. Size Explanation:
   • Millimeters (1 to 100 mm) and micrometers (1 to 100 µm) are much larger than the nanoparticle range.
   • Picometers (1 to 100 pm) are too small and typically relate to atomic scales rather than particulate matter.

The Correct Answer

The correct choice for the size range of nanoparticles is: c) 1 to 100 nanometers.

This characteristic size range is crucial for applications in various fields such as medicine, electronics, and materials science.
