The Market Online speaks with Biosenta Strategy Advisor Kris Hans, as a University of Calgary team has developed a groundbreaking way to turn limestone into bacteria-killing nanoparticles.
Transcript
00:00Welcome back to The Watchlist. I'm Lindsay Melchuk. A research team at the University
00:09of Calgary in collaboration with Biocenta has developed a groundbreaking method to convert
00:14limestone into a potent long-lasting antimicrobial nanoparticle, offering a significant advancement
00:22in the fight against harmful bacteria and fungi. Now here to explain more about this collaboration
00:28is Chris Hans, Strategy Advisor for Biocenta. Welcome Chris. This is some exciting news. Why
00:34don't you tell us a little bit about that? Absolutely. So imagine picture everyday limestone,
00:39but we mill it down to a nanoparticle, wrap it in a protective shell. So in these University
00:45of Calgary tests, our tri-filler nanoparticle killed 100% of some of the nastiest germs we face.
00:52E. coli, so the food poisoning bug that we all know. MRSA, the antibiotic-resistant staph that
01:01plagues hospitals. Pseudomonas, it's a stubborn, water-loving bug. And it did so with one of the
01:09lowest doses ever reported while staying active long after bleach or alcohol would have evaporated.
01:16So if we take this just a little bit further then, what are some of the possible applications for
01:21this tech? In the bigger picture, what it all means for Biocenta? Yeah, so a tri-filler is a dry powder,
01:27so you can drop it straight into paint, concrete, drywall mud. So the surface keeps disinfecting
01:34day after day. That gives Biocenta two fast tracks. We can supply the additive to coatings,
01:42building materials makers. And then the second part, we could license the technology worldwide
01:48once our Health Canada and the U.S. EPA approvals land. The payoff would be cleaner hospitals,
01:56safer transit systems. It'll generate global revenue for us that scales with every bucket of
02:03paint or cement or bag of cement that you would put out. So with that, if you put that into the
02:10material, is it going to dilute or change the chemical dynamic of that material?
02:16It does. And in fact, what it's done is it actually makes it, depending on the concentrations,
02:24and so for instance, with cement, it has made it stronger. So it's, you know, the actually,
02:32it can last longer, stronger, has the antimicrobial benefits as well.
02:37Well, this has been a great chat, and do come back and teach us more soon.
02:43All right. Thank you.
02:45Again, that was Chris Hans, strategy advisor for Biocenta Inc. You can read more about this and
02:51what else the company is up to over on their website at biocenta.com. I'm Lindsay Melchuk.
02:57We'll see you next time.
