I just checked in my trusty Fisher Scientific catalog, and there are lots of different filters in the range of 0.2 microns and above, and many down to 0.1 microns. I did find one interesting entry, Alumina matrix filter membranes from Whatman, in 0.2 micron, 0.1 micron, and 0.02 micron!! Not cheap, but would give you a decent idea of what concentration of bioactive particles you have. So careful filtration/separation techniques could be used. Be well, Mike D.
