Mechanisms and Benefits - Nanotechnology

What is Nanotechnology?

Nanotechnology is a branch of science and engineering devoted to the design, production, and application of materials and devices whose smallest functional organization in at least one dimension is on the nanometer scale (one billionth of a meter). This technology promises revolutionary advancements in various fields, from medicine to electronics.

How Does Nanotechnology Work?

The mechanisms of nanotechnology typically involve manipulation at the nanoscale. This can be achieved through various techniques, such as top-down and bottom-up approaches. The top-down approach involves miniaturizing existing structures, while the bottom-up approach builds materials atom by atom or molecule by molecule.

What are the Key Mechanisms in Nanotechnology?

Self-Assembly: This process allows molecules and nanostructures to automatically arrange themselves into functional structures without external guidance.
Quantum Dots: These are semiconductor particles a few nanometers in size, having optical and electronic properties that differ from larger particles due to quantum mechanics.
Nanoscale Fabrication: Techniques like electron beam lithography and atomic layer deposition are used to create nanoscale patterns and structures.
