What are Manufactured Nanomaterials?
Manufactured nanomaterials are materials intentionally produced to have specific properties or functions through the manipulation of matter on an atomic or molecular scale. These materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts due to their nanoscale dimensions, typically ranging from 1 to 100 nanometers.
Types of Manufactured Nanomaterials
There are a variety of
manufactured nanomaterials, each with distinct characteristics and uses. Common types include:
-
Carbon Nanotubes (CNTs): Cylindrical nanostructures composed of carbon atoms arranged in a hexagonal lattice.
-
Quantum Dots: Semiconductor nanoparticles that exhibit quantum mechanical properties.
-
Nanowires: Ultra-thin wires with diameters on the nanometer scale.
-
Fullerenes: Carbon molecules in the form of hollow spheres, ellipsoids, or tubes.
-
Metal Nanoparticles: Nanoscale particles composed of metals like gold, silver, and platinum.
Applications of Manufactured Nanomaterials
Manufactured nanomaterials find applications across various fields, including:-
Medical: Used in drug delivery systems,
cancer treatment, and imaging.
