If there are microplastics the size of blood cells (this is a range, as cells are differing sizes), how do you filter for blood cells only? You can dual filter

You can dual filter, smaller and larger than, but you'd still have plastics.
- ahupp 4y agoAh, I see, sorry for missing your point. In the paper they injected particles of size "9.55 µm, 1.14 µm, 0.293 µm", and it looks like a red blood cell is 8um. So a purely mechanical filter that got red blood cells would retain the largest of those particles but potentially not the rest. But plasmapheresis uses a combination of centrifugal separation and filters so may be more or less effective than that depending on the properties of the cells and plastics.
- b112 4y agoAh! I was not aware that more than filters were being used. This could certainly help. Thanks
