Facile Green Biofabrication of Nanocrystallites
To facilitate widespread applications of engineered nanoparticles, researchers are looking at novel and better synthesis strategies. This brief chapter details the biofabrication/biosynthesis of nanoparticles, advantages of biofabrication over conventional chemical or physical routes of synthesis, and the mechanism involved in biofabrication. An illustration on the biosynthesis of silver nanoparticles using the metal-reducing bacterium S. oneidensis will be presented as an example. Further, details on the synthesis methodology, physical characterizations with respect to morphology, crystallinity, surface properties, and size and shape distributions, which will be based on characterization techniques involving UV–Vis and Fourier transform infrared spectroscopy, dynamic light scattering, X-ray diffraction, transmission electron microscopy, and atomic force microscopy measurements will be discussed.
