Fast and Facile Synthesis of Stable and Biocompatible Silver nanoparticles Stabilized by Polyethylene Glycol

Jain S., Singh S., Pillai S., Alabama State University, US

Silver nanoparticles show enhanced properties, when supported onto a substrate and incorporated into organic or inorganic matrix. Their remarkable properties are shape and size dependent. Ethylene glycol and its polymers are environment friendly or environmentally [...]

Circular dichroism spectroscopy of Lysozyme-Silver Nanoparticles complex

Ashrafpour S., Tohidi Moghadam T., Ranjbar B., Tarbiat Modares University, IR

The outstanding optical and antibacterial properties of silver nanoparticles have attracted great deal of interest amongst nanobiotechnologists. Designing hybrid systems of nanoparticles and biomolecules as drug nanocarriers of enhanced properties has paved the way for [...]

Combined utility of dynamic light scattering and surface plasmon resonance characteristics for drug nanocarrier systems

Ashrafpour S., Moghadam T.Tohidi, Ranjbar B., Tarbiat Modares University, IR

Study of plasmonic nanoparticles and their interaction with biomolecules has attracted great deal of attention due to potential utility in a wide variety of areas, such as drug nanocarrier systems. However, to enable full exploitation [...]

Single Crystalline Micrometric Iron Oxide Particles with Superparamagnetic Behaviour for MRI Applications

Kiss M.L., Chirita M., Beljung C.A., Polanek R., Savii C., Ieta A., Ionut Mihaila Chirita A., State University of New York at Oswego, US

A major drawback of using metal oxide nanoparticles as contrast agent in MRI is related to their low saturation magnetization mainly due to their particle size. The current works seeks to solve this problem by [...]

X-ray Reflectometry of Planar Nanoheterostructures:a New Model-less Approach

Ustinov V.V., Babanov Yu.A., Salamatov Yu.A., Institute of Metal Physics, RU

X-ray reflectometry is a highly sensitive non-destructive method of the electron density profile determination in multilayer nanostructures. To evaluate the density variation with depth from the reflectivity data one uses traditionally the least squares method. [...]

Multiangle dynamic light scattering for the improvement of multimodal and polydisperse particle size distribution measurements

Boualem A., Ferre C., Jabloun M., Jalocha A., Naiim M., Ravier P., CILAS, FR

This work brings a new and improving method to the determination of multimodal and polydisperse particle size distribution by Dynamic Light Scattering. In this context, we develop a Bayesian method for the estimation of the [...]

The methodology and the software for the analysis of the atomic density modulation underneath the surface of a nanocrystal

Gierlotka S., Skrobas K., Stelmakh S., Palosz B., Palosz W., Palosz B., Palosz W., Institute of High Pressure Physics PAS, PL

Internal structure of nanocrystals can be extracted from Pair Distribution Function, which is obtained by Fourier transform of the diffraction data. Such a transform, G(r), contains complete information on inter-atomic distances present in the investigated [...]
