CHAPTER 7: Acids

The chapter overviews the different types of acids used in the synthesis of nanoparticles particularly classified as carboxylic acids, phenolic acids and amino acids. The mechanisms involved in the synthesis of various nanoparticles such as iron, copper, gold, silver, etc., are discussed in detail. The effects on the mode of aggregation of metal atoms and the particle size of colloidal nanoparticles due to the presence of acids have been discussed as a function of the varying degrees of concentrations of the reagents involved.
