What Is Nanotechnology?
Nanotechnology is concerned with nano-scale materials and structures. Nano-scale refers to particles and devices that are less than 100 microns in size. A sheet of paper has a thickness of 100,000 nano-meters, while a person who stands six feet tall has a thickness of 2 billion nano-meters! The properties of materials at the nanoscale can vary significantly, providing unique functionalities and applications for technology.
What Are Nanomaterials?
Generally, nanomaterials range from 1 to 100 nanometers in size and have unique properties that enable them to be used in technology, such as large surface area, bio-compatibility, optical properties, and electrical properties. Nanomaterials can be divided into four main categories: nanoparticles, nano-fibers, nano-tubes, and nano-aminates.
Applications Of Nanotechnology
Medicine
Many therapies and drugs used to treat chronic conditions, such as cancer and brain tumors, have serious side effects for patients. This is where nanoparticles come in. The drug will only affect the affected cells and not the whole body. Different types of nanomaterials are also used to enhance the performance of imaging systems. The medical applications of nanotechnologies are not restricted to the above-mentioned areas but also cover gene therapy, wound care, and more.
Electronics and Devices
With the development of technology, we’ve gone from big TVs and mobile phones to small TVs and smartphones. Nanomaterials such as Graphene have also been used to create thin, lightweight, and high-quality TV screens that are also energy efficient!
Textiles and Fabrics
Specialty fabrics containing nano-sized particles of Silver and Titanium are used to create a fabric that can be worn, wrinkle-resistant, and smell-free year-round. This has resulted in the development of lightweight, thin, and br ..
