What is Nanotechnology?

Nanotechnology is a field of science and engineering focused on the design, synthesis, and application of materials and devices on the nanometer scale (1-100 nanometers). This domain leverages the unique physical, chemical, and biological properties of nanoscale materials to innovate across various industries.

What are Common Experimental Techniques in Nanotechnology?

There are several experimental techniques used to study and manipulate nanoparticles:

Atomic Force Microscopy (AFM): AFM is used to capture high-resolution images of surfaces and measure forces between atoms and molecules.
Scanning Electron Microscopy (SEM): SEM provides detailed images of sample surfaces by scanning with a focused beam of electrons.
Transmission Electron Microscopy (TEM): TEM allows for the study of the internal structure of thin samples at atomic resolution.
X-ray Diffraction (XRD): XRD helps in determining the crystalline structure of nanomaterials.
Dynamic Light Scattering (DLS): DLS measures the size distribution of small particles in suspension.

How Do We Synthesize Nanoparticles?

Nanoparticles can be synthesized using various methods:

Top-Down Approach: This involves breaking down bulk materials into nanoparticles through methods like milling and lithography.
Bottom-Up Approach: This method builds nanoparticles from atomic or molecular components using techniques such as chemical vapor deposition and sol-gel processes.
Green Synthesis: Environmentally friendly methods using biological agents like plants and microorganisms for nanoparticle synthesis.
