Introduction to Nano Structures

Nano structures refer to materials and systems engineered at the nanometer scale (1–100 nm) that exhibit unique physical, chemical, and biological properties. Understanding nano structures is essential for innovations in medicine, energy, electronics, and materials science.

What are Nano Structures?

Nano structures are engineered forms of matter with at least one dimension in the nanometer range. They can be classified based on their dimensionality and include:

Types of Nano Structures:

Zero-dimensional: Nanoparticles, quantum dots

One-dimensional: Nanotubes, nanorods

Two-dimensional: Graphene sheets, nanofilms

Three-dimensional: Nanoporous materials, nanocomposites
