I don't know as "colloidal" silver is truly a colloid; I
think it's just silver ions in solution, in which case it's no
different from using soluble silver.
I've been using silver nitrate in some cultures to control
ethylene- a common practice. I haven't seen a difference in
contamination, but I've not studied it for that reason. I do know
some folks in tissue culture have used silver with some success to
control bacterial contamination, but have no idea of the concentrations.
