Ceria nanoparticles have attracted a great deal of concern about their impact on human health and the environment due to their widespread applications. [...] The results suggested that surface charge density was closely involved in the cytotoxicity of ceria nanoparticles for E. coli. This work as a well-designed comparison study contributes to a better understanding of the charge-associated biological effects of nanomaterials.

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
