Characterization of Biogenic Nanoparticles Via In-Situ Correlative Secondary Electron Helium Microscopy and Secondary Ion Mass Spectrometry

Over the past several years, the use of both nanoparticles and nanostructured surfaces have emerged as alternatives to the use of antibiotics. Indeed, nanoparticles decrease bacterial survival without being highly toxic to mammalian cells. These nanoparticles can be composed of a variety of materials including silver, gold, titanium dioxide, zinc oxide, silica, gold-dendrimer nanocomposites, and carbon. More recently, an environmentally safe approach was developed for synthetizing Se nanoparticles in the size range of 90-150 nm using E. coli, Pseudomonas aeruginosa, Methicillin resistant S. aureus
