What Are Nanomaterials and Why Are They Special?
Nanomaterials are materials with at least one dimension between 1 and 100 nanometers. To put that into perspective, a nanometer is one billionth of a meter – incredibly small! At this scale, materials exhibit unique physical and chemical properties that differ significantly from their bulk counterparts. These properties arise from quantum mechanical effects and the increased surface area to volume ratio.
- Quantum Dots: Semiconductor nanocrystals that emit light of specific colors depending on their size. They're used in displays, lighting, and bioimaging.
- Carbon Nanotubes: Cylindrical molecules with exceptional strength, electrical conductivity, and optical properties. They're being explored for use in sensors, solar cells, and advanced composites.
- Graphene: A single layer of carbon atoms arranged in a hexagonal lattice. It's incredibly strong, flexible, and conductive, making it promising for transparent conductors, sensors, and optoelectronic devices.
- Metal Nanoparticles: Tiny particles of metals like gold and silver that exhibit surface plasmon resonance. They're used in biosensors, catalysts, and therapeutic applications.
