New measuring techniques can improve efficiency, safety of nanoparticles

Using high-precision microscopy and X-ray scattering techniques, University of Oregon researchers have gained eye-opening insights into the process of applying green chemistry to nanotechnology that results in high yields, improves efficiency and dramatically reduces waste and potential exposure that can be negative to human health or the environment. Reducing the amount of gold, the material used in the research, in the initial stages of the process used to create nanoparticles allows for better maintenance of the particle size. The use of lower concentrations of the precursor that forms the nanoparticles virtually eliminates their ability to aggregate together and, thus, prevents variations in sizes of the desired end product. These new monitoring and measuring techniques, are vital for understanding what modifications are possible in the processes that grow nanoparticles.
