Dishwashing with chamomile – DLS shows super micelles

Washing dishes with DLS

How does dish washing work?
Surfactants have seemingly magical properties: combine greasy plates with dish washing liquid and hot water and the dishes become squeaky clean again.
So, how does that actually work?
Detergents are often amphiphilic molecules which means that have both a hydrophilic and a hydrophobic end. If the detergent concentration is high enough (that is above the cmc or critical micelle concentration) the fat friendly ends self-assemble into micelles with the water-friendly ends sticking out into the surrounding water.
When the micelles comes in contact with a …

NTA or DLS?

Nanoparticle Tracking Analysis or Dynamic Light Scattering ?
After a recent joint NanoSight and Zetasizer demonstration, I received this set of questions that helps illustrate the core of the issue of these two techniques:
 
 
 
 

Since the Nanosight gives me particle concentration, it’s somewhat straightforward to calculate what % of my Nanoparticles are aggregated. Can I calculate % aggregated particles in the DLS as well?  Or does the varying amount of intensity, and the protein+nanoparticle mixture in the sample confound that calculation?

If I wanted to measure non-spherical particles (for example nanorods), which system …

Meet Malvern and Sysmex at the International Symposium on GPC/SEC and Related Techniques

Together with Sysmex, our distributor in Benelux, we are proud to be Gold Sponsors of the International Symposium on GPC/SEC and Related Techniques, taking place from 26-29th September in Amsterdam.
One of our technical experts, John Stenson, is looking forward to presenting some exciting new data in his talk “Combining multi-detector GPC measurements with ultra-high pressure GPC separations” at 3:30 pm on Wednesday 28th September, and says:
“This presentation will discuss the issues related to dispersion and how these can be minimized. We will then show the first high quality data from a combined multi-detector/ UPLC™ …
