The new Zetasizer Nano ZSP made its first public appearance last week during the exhibits at the American Association of Pharmaceutical Scientists Meeting & Exposition in Chicago, IL. We were very pleased to talk with so many outstanding researchers who expressed interest in the instrument’s expanded capabilities for enhanced protein mobility measurements, protein size and distribution analysis, and microrheology characterization.
During the three days of the exhibit, visitors to the booth asked just about every possible question about the instrument, which kept us on our toes, and the response was overwhelmingly …

Have you heard the saying, “If you give a man a fish you feed him for a day. If you teach a man to fish you feed him for a lifetime?” The statement is widely accepted as a Chinese proverb and teaches in sublime fashion that it is better to teach someone how to do something so they can take care of themselves rather than just hand over the result to them on a one-off basis.
In the spirit of teaching others how to find information for themselves, I’d like to share a …

In a recent issue of Standardization News, I read an interesting article that discussed the development of ASTM nanotechnology standards. Elsewhere in the publication, the president of ASTM International referenced “the spirit of cooperative antagonism” that comes from a cross-section of experts and dedicated professionals who often engage in rigorous debate and contention because they will likely be impacted by the final standards. I simply want to tell you who these people are and thank them for the hard work that they do.
Firstly, Nanotechnology is a discipline that covers areas …

I am regularly asked how long a measurement takes on one of our Zetasizer instruments. I get this question even more frequently when people are asking about our Zetasizer APS (auto plate sampler) dynamic light scattering instrument, which analyzes samples that have been prepared on either 96- or 384-well plates.
It is an intriguing question, and not one with a black and white or definitive answer. Strangely, it often makes me wonder what the person is really asking.
Let me explain
When making light scattering measurements, there are numerous factors that come into …
In these days of global economic worries, civil unrest and uncertainty in many healthcare sectors, scientists and other people associated with the life sciences industries do not often have to be reminded to remain positive. They also do not often question why they’ve chosen their profession nor do they look solely for external incentives to keep them going.
Recently, a viral video hit the internet that perfectly illustrates why many of us do what we do.
In the video, 29-year-old Sarah Churman is shown reacting to the sound of her own voice. …

I encounter many different types of colloid and nanoparticle applications in my routine interactions with customers and we are often asked to analyze such samples for our customers and prospective customers. The range of potential applications for these nanomaterials is truly astounding.
Time and again it has been shown that analyzing metal nanoparticles such as colloidal silver and colloidal gold, using dynamic light scattering and electrophoretic light scattering techniques, helps researchers get a handle on important control parameters such as size, coating/functionalization and stability behavior.
It was with great interest, then, I …
What do the following three statements have in common?
Reading in dim lighting will ruin your eyes.
Eating turkey makes you sleepy because it contains tryptophan.
Dynamic light scattering analysis is not suitable for samples that contain aggregated or agglomerated materials.
These three statements all share the fact that they are myths. Untruths. Poppycock.
I enjoy watching a particular television show with my children called Myth Busters. On the show, the cast tackle what are considered to be common—and sometimes uncommon—beliefs in order to either confirm them or “bust” them. The show’s hosts go about …
Hi. I’m Dave Dolak, U.S. Product Manager for Light Scattering Technologies here at Malvern. I have responsibilities primarily for our Zetasizer line of instruments.
I heard a news story on the radio recently that discussed the financial challenges of electronics retailer, Best Buy, here in the United States and how the company’s stock had just hit a 52-week low. As part of the story, the reporter stated that Best Buy executives are aware that many consumers go to their store to try products, learn more about them and see them physically but …
