Roger,

Surely this investigation is flawed, or at least back to front.

Would it not have been of greater interest to find the most effective
silver colloid, and then determine particle size and method of
production, rather than eliminate subjects (15) according to particle
size, and then test the remaining (4) for efficacy?

The results may well be the same...but what is the reason for making
colloidal silver in the first place.

Regards
Ivan.
