Can we categorize doping and compositing of nanomaterials as a functionalization?
is functionalization include only the surface modification with chemical groups?
I agreed with the Dr.kanyong.
Fuctionalisation involves introduction of functional group or molecules into specific positions that gives them certain character. Eg. Fuctionalisation of silica with a molecule like proline makes it stereospecific. On the other hand the doping is addition of impurity which enhances certain certain properties. Eg. p-n semiconductors materials, mixed metal oxides. Also fuctionalisation is mainly at surface whereas doping may not be necessarily surface related.
Thank you all for sharing your opinions.
Actually, what has confused me is one article I read recently. They considered doping as "ELEMENTAL Functionalization".

This seems to be a situation where the term BULK functionalization might otherwise be explicitly stated to distinguish it from the implicit understanding of functionalization as a surface-related process. However, functionalizing seems also to have two meanings. One is to functionalize a chemical or material to change its chemistry. Adding functional groups to molecules or surfaces via chemical reactions is an example. The other is to functionalize a device to change its performance. Doping can be an example. Doping can be localized to a surface region. In semiconductor devices where the components are placed across a surface, this is indeed the case.
So, the use is confusing until you recognize that chemists and (electrical/chemical) engineers use the same word for different situations.
Thank you Dr. Weimer
I believe you raised a very important point and clarified the confusion.
