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.
