Quick Summary

The nanoscale refers to dimensions measured in nanometers (nm), where 1 nm is one billionth of a meter. At this scale, materials exhibit unique physical and chemical properties due to quantum mechanical effects and a higher proportion of surface atoms.1234

Nanoparticles, with at least one dimension between 1 and 100 nm, possess characteristics distinct from their larger counterparts. These properties can be harnessed for applications in medicine, engineering, catalysis, and environmental remediation. For instance, nanotechnology is already used in products like stain-resistant clothing, invisible sunscreens, and antibacterial bandages. Future possibilities include lighter, stronger materials, improved energy efficiency, and advanced sensors.154
