Featured Research from universities, journals, and other organizations Nanosafety research: The quest for the gold standard Date: October 29, 2014 Source: Swiss Federal Laboratories for Materials Science and Technology (EMPA) Summary: Toxicologists have evaluated several thousand studies on the risks … Continue reading
By its cross correlation method (PCCS) NANOPHOX is able to eliminate scattering information that is not due to Brownian motion as e.g. multiple scatter, cuvette surface inhomogeneity etc.. This results in the best possible raw data for evaluation. In NANOPHOX … Continue reading
This is a translated excert of a chapter from famous Prof. Leschonski’s “Clausthaler Kurs” describing the necessity of large numbers of particles to count for accurate sizing. Random eror PDF
The fear of new unknown technologies is as old as progress itself and often leads to irrational suggestions for coping with it as shown in this image of protection against railway accidents from 1847. read more about it in detail: … Continue reading
An impressive and coherent course about risk evaluation. (Also applicable to nano particle risk evaluation!)
Just recently Toni Harrison on LinkedIn pointed to a very helpfull video regarding risk evaluation done by Peter Sandman. This explains in a coherent way why nano danger pubications gain so much publicity, but also how they gain influence and what they mean whith respect … Continue reading

This is a list of the actually links regarding NANO in the web, state of oct. 2011 . Open the list view
The most complete compendium for nano behavior I could find is: “Intermolecular and surface forces” by Jacob N. Israelachvili issued by Academic Press This forms a reasonable scientific basis for all discussions on nano particles, their properties, interactions and enables … Continue reading
Just for some days there is an interesting discussion going on to: Nano particle counting
You only get what you pay for! Are low budget instruments worth what you pay for it? “Nano” is one of the most attractive and modern terms in research, industry and marketing. Due to the excellent definition work of the … Continue reading
According to the valid definitions in ISO/TS 27687: August 2008 and the standardl particle definitions in accordance with ISO TC 24/SC 4, TC 146 and TC 209 there is a clear definition of nano particles respectively nano objects. Only for … Continue reading
In relation with production and stabilization of Nano-objects there is very often the talk about observing/ setting the right Zeta-potential. Also a lot of actual analytical instruments promote Zeta-potential determination together with e.g. size determination.
NANO is an in many cases even in technical literature incorrectly used term. The Technical Committee 229 of ISO is deserving thanks for an exact definition with respect to particle size measurement in August 2008. (ISO/TS27687). According to this definition … Continue reading
