Dear Abou. I read your paper. I am sorry in your article nanoparticles doped by nanoparticle is not clearly mentioned, as I asked in question. anyway thankful for your attentions

Dear Chem,

I am sorry, it was an error.

This is the paper : Ag/ZnO.

Article Green Synthesis of Ag/ZnO Nanohybrid using Sodium Alginate G...

What is doping you mean? In semiconductor physics doping is "The addition of impurities to a semiconductor to control the electrical resistivity" (see ASTM F1241-95(2000) - Standard Terminology of Silicon Technology), i.e. in the narrow sense. Traditionally these definition expanded in solid state chemistry. Normally doping is substitution of the element on the normal position of the regular crystal lattice by element with a different valence. There is a sport medicine definition also, but I think it is inappropriate here.

Dear Vadim you are saying good. I want to get detail in chemistry. No doubt doping is substitution of the element on the normal position of the regular crystal lattice by element with a different valence. I read many papers but could not find one point '' can we dope resynthesized nanoparticles with nanoparticles.'' people used different methods like sol gel or coprecipitation using different metal salt

As Confucius said: If names be not correct, language is not in accordance with the truth of things. If language be not in accordance with the truth of things, affairs cannot be carried on to success... (ANALECTS. BOOK XIII. TSZE-LU. CHAP. I. 1. 5).

I think that it is more correct to talk about creating agglomerates of various types of nanoparticles, i.e. nanoparticle compositions. The nature and character of the bond between particles can be clarified in the course of research.

Vadim S. Gorshkov I am grateful for your suggestions
