Hi. It really depends on the class of nanomaterial that will constitute the matrix. The doping procedure will be different in case of metallic nanoparticles, oxides or semiconductor (e. g. chalcogenides). However, the general trend is to add the doping precursor at the beginning of your sinthesis, before the nucleation of NPs, in the desired molar ratio (it is assumed 100% yield). For metals, the precursors are typically metal salts, for oxides it could be an alcoxide, an organometallic compound or a complex of the transition metal like acetylacetonate. You should also consider the mechanism of nucleation+growth for your material, I mean, if it is a reduction process (like for metal NPs), a sol-gel process (for oxides) or a thermal decomposition (for some chalcogenides).

Hope this helps.

Dear Kirin,

the easiest way is often to add a metal salt in the synthesis process, often a nitrate, in the concentration you want to have in your final NP. For my purposes it was very successful.

Good luck, Martin

You should have to take a suitable metal salt which react with your primary material(plant extract) like in AgNP we AgNO3 , and Ti-NP we Use TiO2
