Is there (that you know of) any standard for what this term means in this context? Does "highly engineered" mean "of super-uniform size, shape and/or toughness"? The term must have some very specific meanings if it's actually used by anthrax researchers, and that meaning may be revealed by what similar terms convey in related fields of study. I probably should try to cross-post this question to Dr. Ness's blog if appropriate.
I've also been just assuming that centrifuging is the main separation/purification technique, and I've no idea if that would be the case. It's been 22 years since I was a tech in an academic cancer research lab. I can't distinguish a Western blot from my Southern ass.
