What are the different methods of synthesis of nanoparticles?

There are several methods for creating nanoparticles, including coprecipitation, hydrothermal synthesis, inert gas condensation, ion sputtering scattering, microemulsion, microwave, pulse laser ablation, sol-gel, sonochemical, spark discharge, template synthesis, and biological synthesis.

What is turkevich method?

The Turkevich method is a relatively simple and reproducible technique for the synthesis of spherical particles between 10 nm to 30 nm. However, the particles become less spherical, the size distribution becomes broader, and the results were less reproducible for the synthesis of AuNP above 30 nm size.

How do you synthesize nanoparticles?

Nanoparticles are traditionally synthesized using wet chemistry methods, which involve first generating the particles in a solution, drop casting the wet particles onto a substrate, and removing the solvent, surfactants, and other materials from the particles.

What is synthesis of nanomaterials method?

The sol–gel method is a wet-chemical technique that is extensively used for the development of nanomaterials. Conventional precursors for the generation of nanomaterials using the sol–gel method are metal alkoxides. The synthesis process of nanoparticles via the sol–gel method can be completed in several steps.

Why is green synthesis of nanoparticles?

Nanoparticle synthesis using microorganisms and plants by green synthesis technology is biologically safe, cost-effective, and environment-friendly. Plants and microorganisms have established the power to devour and accumulate inorganic metal ions from their neighboring niche.

Why is gold used in nanoparticles?

To minimize aggregation, the versatile surface chemistry of gold nanoparticles allows them to be coated with polymers, small molecules, and biological recognition molecules. This surface modification enables gold nanoparticles to be used extensively in chemical, biological, engineering, and medical applications.

How do you control the size of nanoparticles?

Semiconductor nanocrystals present quantum confinement effects, called Q-dots. To control the size and the shape of nanoparticles reverse and normal micelles, bicontinuous and lamellar solutions have been used.
