is called chemistry. DEVELOPMENT OF CHEMISTRY Chemistry, as we understand it today, is not a very old discipline. Chemistry was not studied for its own sake, rather it came up as a result of search for two interesting things: i. Philosopher's stone (Paras) which would convert all baser metals e.g., iron and copper into gold. ii.

summarizing data on chemistry of gold complexes with organic ligands as precursors for deposition of Au films and nanoparticles are only sporadic and were written more than 10 years ago.
