Agreed. In regards to implants mechanical wear would act as the "polishing agent" to remove silicon dioxide and expose fresh silicon nitride. However can we be completely sure of this given silicon nitrides extreme hardness. I guess we can since there's discussion of silicon nitride wear particulate.

My questions here are mainly regarding novel uses beyond implants such as:antibacterial door knob coatings. Antibacterial, antifungal doped plastics, rubbers and paints. Coatings on personal massagers as antiviral antifungal coatings. Facial masks for acne. Foot creams for fungus. Potential for antifungal doped shoe insoles etc.

it seems he suggests this leaching of ammonia species occurs from a wet silicon nitride surface. Is this suggesting dry applications would not induce the antimicrobial characteristics? For things like facial masks for acne this may be a benefit if so since I assume it would have an infinite shelf life until wetted and thus activated causing the eventual full decay to silicon dioxide where I would consider it spent.

In shoe insoles this may be beneficial since bacteria and fungus need moisture to replicate. If silicon nitride lays dormant until it's antimicrobial properties are activated through moisture.

So shelf life seems important here.

In a fully aqueous environment how long do these antifungal antiviral etc. properties exist until we can consider the material fully expended to a point where these properties are no longer useful or expressed?

I also wonder if contact polishing on things such as door knobs would be enough to polish off the silicon dioxide layer thus exposing the underlying silicon nitride and restoring its antimicrobial benefits. Contact polishing IE touch something often enough with a bare hand and it eventually polishes.
