I am working in my PhD about one medicinal plant doing extraction and isolation the phytochemical and check their biological activities and the last objective of my work Biosynthesis of ZnO Nanoparticles using same plant extract as a reducing agent and a stabilizing agent then charcterisation the ZnO NPs and check their antimicrobial antioxident activites. Is that ok or it is not mached?
Is the green ZnO NPs activity will differ from plant to other plant extract?
Thank you in advance

If you compare well-purified ZnO nanoparticles of the same size obtained with different extracts, then their properties should not differ. However, you know that in different extracts there will be different substances and they will affect the shape, size, adsorption of other molecules. Sometimes it happens that it is not possible to obtain the same nanoparticles. Everything must be proved by their characterization.
Saif Ali There are an infinite number of 'plant extracts' all with differing make-up of reducing agents (if any) and stabilizers (if any). Indeed even a single plant extract will change from season-to-season in all likelihood. Each plant extract will have its unique properties and chemistry. Thus any produced (ZnO) material is likely to be different in terms of size distribution, shape, and activity. My other comment would relate to formation of Zn(OH)2 in aqueous systems rather than ZnO (probably produced by calcination meaning that there are no separate discrete independent particles < 100 nm in the powder)... I assume you've looked at XRD for the produced materials to confirm ZnO and not Zn(OH)2...
