What is Nanotechnology and its applications?

Nanotechnology:

• Definition: Manipulation of matter on an atomic, molecular, and supramolecular scale at nanometer dimensions (1 to 100 nanometers).
• Key Materials: Carbon Nanotubes, Graphene, Quantum Dots, and Nanoparticles exhibiting unique physical/chemical properties.
• Applications: Targeted drug delivery (cancer therapy), nano-fertilizers, water purification (nano-filters), and flexible electronics.
