What bothers me most about the article is that the research claims that bacteria will gain resistance to this method of treatment. This is a physical process, much like heating bacteria causes them to rupture and freezing causes ice crystals to shred them.

Titanium dioxide won't directly affect any micro-organism. However, when you throw some water and UV light into the mix, titanium dioxide catalyzes the breakdown of water into hydroxyl particles: OH.

These particles love to grab onto free electrons and thus disrupt DNA (data corruption!). This in turn prevents the bacteria from replicating. Look up advanced oxidation treatment if you want to know more about this mechanism.

I am not a biologist but getting my BS in Civil engineering I took a few classes covering this kind of treatment.
