Green chemistry is the use of chemical techniques, routes and methodologies that decrease or eradicate the use or production of feedstock’s, products, byproducts, reagents and solvents, etc. that are detrimental to human health or to their environment. Thus, the main objective of green chemistry is the reduction of hazardous substances associated with processes and products that are crucial to the economy of the world and to maintain the quality of life that we enjoy through green chemistry.

For green synthesis, substances that are synthesized by plants are used. Very often, metal ions to metal nanoparticles are regenerated with plant extracts that contain ascorbic acid, rutin, flavonoids, and other reducing agents. For chemical synthesis, inorganic reducing agents borohydride, hydrazine hydrate are used, which are obtained by inorganic synthesis.

I agree with Yuri

In chemical synthesis of nanoparticles, substances used as reducing agent are from chemical sources while as in green synthesis, the reductant is usually from a biological source which may be bacteria, fungi, plant part etc. Green synthesis of nanoparticles reduces or eliminates the use of substances which are hazardous to humans or environment.

Yuri Mirgorod Thank you for your kind information.Sounds good, indeed, plants are now used in nanotechnology. However, let me know which type of plants (leaf) are used in nanotechnology, lately?

ascorbic acid - dogrose, orange, mandarin

rutin - tea, motherwort

chemical synthesis:

- chemical reduction method using hazardous chemicals like sodium borohydride as reducing agents

-use of toxic chemicals on the surface of nanoparticles and non-polar solvents in the synthesis procedure

green synthesis:

- clean, biocompatible, non-toxic and eco-friendlybiological route of nanoparticle synthesis

- using Biological materials such as bacteria, fungi, yeast, algae and plants as reducing and capping agent

- More stable nanoparticles

Better control over size and shape of nanoparticles

As mentioned above, the use of Ascorbic acid, carbohydrate for the reduction is also a green methods
