It would be interesting if something like Brilacidin could be aerosolized and blown through forced-air ventilation systems to wipe out black mold and other things.
As far as Karin's articles, it's always easier to panic people out of their investments than to get them to put new money in -- so don't expect the kind of reaction we have sometimes seen to the bear articles. It may take longer for people to pay attention to a positive article than to a negative one.
It would certainly be an interesting question to ask Leo by email. Seems it might be possible to just begin the process with the EPA. I imagine it is all hands on deck with Brilacidin at the moment though. Thinking of things like antibacterial light switches (bathroom), airplane tray tables etc. Could even be an asset to sell out right to fund trials.
Brilacidin might make a more potent, and more environmentally benign, anti-bacterial than Triclosan, if its topical time-of-action is 2 minutes or less. That would be a mass-market application worth billions. Have no idea about feasibility or sustainability, just speculating here.
