What IsNanotechnology
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
What is Nanotechnology?
How Small Is Nanoscale
A nanometer is…–one billionth of a meter
How Small Is Nanoscale?
Human Hair: Approx. 1x105 nmDNA Sample: Approx. 2 nm
Seeing at nanoscale
Nanoscientists use high-powered microscopes that use unique methods to allow them to see the surface features on the atomic scale, effectively opening the door to modern nanotechnology such as scanning tunneling microscope and the atomic force microscope.
Manufacturing at the nanoscale
Nanomanufacturing involves scaled-up, reliable, and cost-effective manufacturing of nanoscale materials, structures, devices, and systems.
It leads to the production of improved materials and new products.
How it works?
Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.
We All Should Care!–Because it can bring revolution in the current
industrialization and manufacturing processes.
