What is Nanotechnology?
Nanotechnology is the science, engineering, and application of materials and devices with structures and components sized between 1 and 100 nanometers. At this
nanoscale, unique physical, chemical, and biological properties emerge, distinct from their bulk counterparts. These unique properties enable novel applications across various domains including medicine, electronics, and energy.
What are Nanoscale Technologies?
Nanoscale technologies refer to the tools, techniques, and methods used to manipulate and fabricate materials at the nanometer scale. This includes the creation of nanoparticles, nanowires, and nanocomposites, as well as the development of nanoscale devices and systems. These technologies leverage the unique properties of nanomaterials to achieve unprecedented levels of performance and functionality.
How are Nanoparticles Created?
Nanoparticles can be created through various methods such as
chemical vapor deposition, sol-gel synthesis, and ball milling. Each method offers different advantages and is selected based on the desired properties of the nanoparticles. For instance, chemical vapor deposition allows for precise control over particle size and composition, while ball milling is a more cost-effective method for producing large quantities of nanoparticles.
What are the Applications of Nanoscale Technologies?
Nanoscale technologies have a wide array of applications. In
medicine, they are used for targeted drug delivery, imaging, and diagnostics. In
electronics, nanoscale materials are utilized to create smaller, faster, and more efficient devices. In the field of
energy, nanotechnology is used to develop more efficient solar cells, batteries, and fuel cells. Additionally,
