 I need everyone to understand this. Gone are the days where if you don't see it on a scan, does it mean that you don't have a malignant collection of cells for that little data to send? Absolutely. And we have now sensitive methods more and more that will help the pathologist who either doesn't see anything on the biopsy or the imager who doesn't see anything on the MRI or the PET scan or the CT scan. We now have blood-based, sensitive techniques, which will help them in those ones where they're very suspicious, but they just don't see anything, help them get those guys to more aggressive treatment and will save those people's lives. But exosomes probably have as well that same targeting capability that a biologic does. But we might be able to either do combinations or other kinds of treatments inside of the cargo. That's crazy. That's crazy. Wouldn't that be cool? That would be so cool. We can put therapeutic viruses in there. We can put all sorts of stuff that might really tilt people into a better outcome.
