Dude. Give it up. Wife is a neurologist and we are working with a pharmaceutical company on drug development for a rare childhood disorder.

Just because I pointed out a gap in your BBB knowledge, you don't have to try to convince me of your knowledge.

It is binary. Do you want to stick with particle size does not matter? This isn't about who has a longer member or can write their name in the snow.

Well, I’ve worked with a few pharm companies on various projects, including drug development so no need to state your wife’s credentials. Is she a physician with neurology boards or just a PhD? I’ve also had a project funded on BBB disruption to allow blocked molecules to enter. The BBB is damn tough to breach. You should know that. Maybe you are a small virus expert and are aware several can cross the BBB? Your screen name touts you as an engineer?
