By Protocol I mean which substance add first ? which add next ? And which in the last and tell me is there is necessary sequence of adding precursor metal salt,reducing agent,base,acid and capping agent etc ? Which protocol gives best results ? Kindly tell me the every step one by one in a very simple way without recommending any research paper,Thanks in advance.
You can prepare metal nanoparticles by physical,chemical and biological synthesis methods. In chemical synthesis, you are generally required to add the metal salt in distilled water or Deionised water or double distilled water or any other solvent according to the application involved. After stirring and dissolving the salt you can add the reducing agent very slowly, preferably drop-wise with continuous stirring. Some metals such as Copper also require some heat treatment so you will have to read up for that. After a certain period of time, you can add your capping agent like PEG, PVP, etc, or you can even use a surfactant for capping. Hope this helps.
Thanks Renukka,would you tell me what happened if the sequence of adding the all involved substances be change ?
Dear Mr.Yuri Mirgorod kindly give your valuable suggestions about my above question,when ever you get free.
Thanks
Taking an example of Gold Nanoparticles, Kindly go through the link and read under the section titled-"Mechanism of formation, encapsulation, and stabilization of GNPs"

Thank you so much again,dear Renukka and khushdeep for your response.your answer really help me.
