Question

the nano particles can be synthesized with the help of​

Answer 1

Answer:

Nanoparticles can be derived from larger molecules, or synthesized by 'bottom-up' methods that, for example, nucleate and grow particles from fine molecular distributions in liquid or vapour phase. Synthesis can also include functionalization by conjugation to bioactive molecules.

Explanation:

Answer 2

Nano particles can be synthesized with the help of physical, chemical, and biological methods.

• Uniform-sized and long-term stable nanoparticles are obtained through physical and chemical methods of synthesis.
• Biological synthesis can be achieved either by transporting ions into microbial cells (intracellular method) or by trapping metal ions on cell surfaces (extracellular method) with the help of enzymes.
• Physical synthesis is carried out by two methods called Top-down and Bottom-up approaches, in which either the break down of bulk material into nanosize or the build up of atoms or molecules into nanosize is carried out.
• Polyol method, hydrothermal synthesis, wet chemistry methods, and other chemical methods are used for nanoparticle synthesis.
