What is Nanotechnology?
Nanotechnology is the understanding and manipulating materials at the nanoscale, or between 1 and 100 nanometers, where special phenomena enable cutting-edge applications, is known as nanotechnology. Nanotechnology encompasses nanoscale science, engineering, and technology in fields such as chemistry, biology, physics, materials science, and engineering and involves imaging, measuring, modeling, and manipulating matter at this length scale.
A human hair on an average has a width of 70,000 nanometers (nm). Aquaritin particle size is between 1 and 30 nm.
What is the focus of Nanotechnology?
The use of nanoscale structures, devices, and systems result in new form with at least one new or superior characteristic or property is the main focus of nanotechnology. Its main target is to comprehend, create, and make use of materials and structures with special qualities and behaviours that develop at the nanoscale as a result of quantum phenomena and increasing surface area. Nano structures are incredibly intricate and exhibit the technology of the present and the future with countless potential applications in almost all facets of life!
How does Nanotechnology differ from regular materials?
The nanomaterial that can be produced or even improved with the use of nanotechnology is astounding. According to ISO/TS 80004, a “nanomaterial” is a “material with any external dimension in the nanoscale or having internal structure or surface structure in the nanoscale,” with the “length range approximately from 1 nm to 100 nm” being the nanoscale. Both nano-objects, which are discrete pieces of material, and nanostructured materials, which have internal or surface structure on the nanoscale, are included in this; a nanomaterial may belong to either of these categories. In essence, nanomaterials can differ greatly from bulk materials, opening up new possibilities for innovation in a variety of fields, including electronics, medicine, materials science, energy, and more.
Is Nanotechnology New?
Nanoscale materials have been utilized for centuries, despite the fact that current nanoscience and nanotechnology are comparatively recent. Colors in the stained-glass windows of medieval churches hundreds of years ago were produced using gold and silver nanoparticles. In the past, artists could also modify materials at the nanoscale, which enhanced the material’s properties. In British Museum, the stunning Lycurgus cup reveals a brilliant red when light passes through its sections of glass containing gold-silver alloyed nanoparticles.
How are Nanomaterials Fabricated?
Nanomanufacturing involves scaled-up, reliable, and cost-effective manufacturing of nanoscale materials, structures, devices, and systems. It includes research, development, and integration of two approaches for the manufacturing of nanomaterials: The “top-down” approach, which entails disassembling of large pieces of material to generate the required nanostructures from them e. g. metal nanoparticles and the “bottom-up” approach, which implies assembling single atoms and molecules into larger nanostructures e. g. dendrimers, nanofilms for coating, nanosensors.
