Nanotechnology is the science and engineering of manipulating matter at the nanoscale - typically between 1 and 100 nanometers - where materials exhibit unique physical, chemical, and biological properties. Operating at this incredibly small scale (a nanometer is one billionth of a meter), nanotechnology enables breakthroughs across multiple industries, from healthcare and electronics to energy and environmental science.

What Is Nanotechnology?

At the nanoscale, materials behave differently than in bulk form due to quantum effects, increased surface area-to-volume ratios, and scale-dependent properties. These unique characteristics allow scientists and engineers to design new materials and devices with enhanced strength, conductivity, reactivity, and more.

Key principles include:

• Quantum Effects: Materials show novel electrical and optical behaviors.

• Surface Area to Volume Ratio: Increased reactivity and interaction potential.

• Self-Assembly: Nanoparticles can organize into complex structures naturally.

• Scale-Dependent Properties: Chemical and physical properties vary with size.
