I am working for my PhD in Nanotoxicology from University of Calcutta. I have a query regarding nanotoxicology study. In many papers i have seen researchers using surfactant to prevent nanomaterials from being aggregated. But is that really needed?? I guess nanomaterials once inside the system would also agglomerate as it has its inherent property to do so under physiological conditions. And moreover if we consider an aquatic environment it would form aggregate there also, so why are we more interested to see the effect of nanomaterials, as in monodispersed, in the nano range rather than what it would be in nature. If we want to mimic the natural condition why don't we use water from natural source. I guess that would make more sense as it is where nanomaterials would get deposited, and not in the lab in Hoagland's or PBS or RPMI, with tween in it.

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 editor@nanopaprika.eu
