Russian scientists to cover viruses in gold

Recently, word has been appearing in scientific literature suggesting that collaurin can activate the immune system response to foreign antigens. Researchers at the Institute of Biochemistry and Physiology of Plants and Microorganisms, Russian Academy of Sciences, and the State Scientific Institution of Saratov Research Veterinary Station of Russian Agriculture Academy; have proved that gold nanoparticles increase…

Russian scientists are studying light sources

For many experiments, it is important to know the exact wavelength of the source of light. Unfortunately, wavelengths of lasers or light-emitting diodes are subject to change depending on the environment factors such as ambient temperature. Those changes that can be as significant as a fraction of a nanometer are important for exploring the structural positions of ions in metals. Today, equipment is calibrated using emission spectrum analysis (spectrophotometric method) but this is a…

Russian researchers have studied elastic properties of graphene

As of today, graphene, the thinnest one-atom-thick layer of carbon, is one of the most amazing materials. Measurements made in 2008 by researchers at Columbia University, proved that graphene was also the strongest and most elastic material among all known ones. However, the obtained data related to “ideal” graphene, which contains very few admixtures, its crystal structure being homogeneous. Apparently, defects in its structure should…

Russian researchers forecast nanoparticles dimensions

Enormous free surface area, unique magnetic and optical properties of nanoparticles provide great opportunities for their application. One of the easiest and most efficient methods for getting nanoparticles is mechanical milling of larger-particle powders. Solving specific process tasks often requires nanoparticles of fixed composition and dimensions, but the existing models of obtaining them are rather experimental data integration and can hardly help in selecting powder processing…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at

Dr. András Paszternák, founder of Nanopaprika

Next partner events of TINC

We are Media Partner of:
