About Biological Nanoparticles and Microparticles 

Biological nano- and micro- particles refers to the group of bodies (cells, viruses, vesicles) ranging from 1 to 1 000 nm in size. This encompasses bacteria, algae, plankton, viruses, chromosomes, and extracellular vesicles including oncosomes, exosomes, and microvesicles. A couple of examples: increasingly, scientists are researching the power of extracellular vesicles as a non-invasive indicator of certain diseases and cancers, as an intercellular communication channel whereby the cargoes control basic cellular functions, and as a potential drug delivery mechanism. Marine scientists are able to utilize advanced sensitivity to determine minute differences between phytoplankton populations and to visualize ocean viruses ahead of genetic characterization.

Beckman Coulter Life Sciences offers state of the art instruments uniquely equipped to power researchers discovering the very edge of biology. Their ideas combined with our expertise gives those exploring the nano scale of biology the tools to succeed.

Looking Under the Hood: Getting Started with the Optima AUC In the webinar we discuss the fundamentals of analytical ultracentrifugation and look at a few sample applications.
Webinar: An Intro to Characterization of Biomolecules Using AUC Analytical Ultracentrifugation (AUC) is one of the most powerful biophysical tools used today for the characterization of biological samples ranging from small drug molecules to intact viruses, vesicles and microparticles
Analytical Ultracentrifugation in Nanoparticle Analysis Joshua Robinson covers the utility of fractionation in the investigation of complex mixtures and polydisperse samples as well as versatility of analytical ultracentrifugation (AUC) for colloid chemistry. He quickly reviews analytical ultracentrifugation (AUC) theory, then discusses deconstructing nano-constructs and how AUC has been used in recent literature to really probe the underlying structure of nano-constructs, nanomaterials. Other topics covered include nanoparticle sample preparation, as well as Beckman Coulter's research and future perspectives.
Extracellular Vesicles for ‘Liquid Biopsy’ Development in Cancer by Dr. Karla Williams Using nano-scale flow cytometry, the Williams lab has identified a secondary bio-marker that allows them to identify the most critical prostrate cancer in patient samples. This revolutionary discovery has the potential to reduce unnecessary needle biopsy surgeries because only a blood sample is needed, as well as reduce overall costs to test for the disease. The Williams lab expects to move to clinical trial phase in the coming months. 
Physical and Chemical Characterization of Nanoparticle Constructs Using the Analytical Ultracentrifuge Webinar covers physical and chemical characterization of nanoparticle constructs using analytical ultracentrifugation. Webinar is presented by Osman M Bakr from King Abdullah University of Science and Technology.
