How Surfactants Control Crystal Growth of Nanomaterials

Exciting characteristic features of nanomaterials in contrast to their bulk phase require shape control of morphologies at the nanometer scale. Surfactants, a unique class of surface active molecules, possess remarkable ability to control crystal growth and direct it in shape and size controlled manner. The fine-tuning of the desired morphologies can be achieved by controlling the surfactant architecture as well as its self-assembly behavior. This review highlights the correlation between the surfactant properties and their ability in designing nanomorphologies. In terms of future perspectives, the methodologies can also be implemented to design biologically sustainable nanomaterials for their possible use in nanomedicine.
