Can microbubbles be pelleted by centrifugation? In short, no. At least not a pellet that you would see at the bottom of your tube when you spin down cells. Instead, what happens is anything with a density greater than water sinks and sinks faster when in a centrifuge. And anything with a density less than water rises and rises faster when in a centrifuge. How Microbubbles Float When Centrifuged So, …

The Physics of How Microbubbles Sort Cells

microbubbles

Flotation is the driving principle behind our cell sorting technology. It’s hard to imagine many other physical phenomena that humans have more of an intuition for than floating and sinking. The exact same rules of floating and sinking apply to a stem cell being lifted from a sample on the back of an Akadeum microbubble. In principal, it is as simple as pair of water wings that keeps a two-year-old …
