how a cobalt nano-particle can be synthesized by using plant extracts...? is any reference article available...?
There are many method to develop cobalt nano particle. By strire method, direct sun light method, etc
How can I prepare a cobalt oxide nanoparticle in a simple green method? And also please suggest the precursors for the synthesis?
@Alan F Rawle: i am in blank which one to be used as a source sir.. my purpose of the study is to be used as a dietary inhibition.
@Alan F Rawle: using cobalt chloride as a precursor and a plant is using as a reducing and stabilizing agent...

It is likely that you'd need to complex the cobalt to the hexammine form by using ammonia (see for example: https://www.youtube.com/watch?v=3ba7RoQVs9o). This will give a stable solution capable of reduction. The plant material is up to you to discover...... (Steric) stabilizing agents such as low concentrations of PEG or PEI (~ 50 kDa) may be needed to prevent the nanoparticles from aggregating and sedimenting.
@ M. Farooq Wahab · Indeed. The expensive item here is the cobalt salt rather than any employed non-reproducible plant extract. Hence the preparation of controlled size and stable Co nanoparticles is better effected and controlled by appropriate reducing agents that can be obtained in high purity. These include citric acid and citrates (Turkevich), ascorbic acid, glucose, fructose, sodium borohydride, formaldehyde, SnCl2, hydrazine hydrate (as I used in my Ph.D for other metal colloids) even hydrogen gas.....

@ M. Farooq Wahab Yes, I agree. It's the lack of control in terms of the (plant material) reducing agent that causes major issues even before fraudulent postings in obscure journals. Pity Peter Kapusta is no longer on ResearchGate - he'd have some entertaining things to say about plant material in a vein similar to yours. I miss his postings.
@M. Farooq Wahab why is it a scam reserch? I was looking at starting my PhD research on those.
