Is it too late to add the capping agent?

All reducing agents that we recommend, also act as capping agents. All capping agents except gelatine, also act as reducing agents.

Thank you so much! A direct answer all in one place. Gelatine caps the best but will not act as a reducing agent. Perfect.

Just remember that you can't "cap" ionic products, nor would you need to.

An ionic product will be instantly turned into chloride in the stomach.

Okay, now I need clarification again. Isn't the current protocol to make ionic, then reduce it to a colloid, then cap it? Or does using an electrolyte skip ionic and go straight to particles?

Nearly.

Using an electrolyte stops plate-out and keeps the current even.
Using the reducing agent reduces the ionic silver oxide into nanoparticles.
Most reducing agents also cap the particles with varying degrees of success.

The process happens in that order.

What is plate-out?
Thanks

What we want, is for the silver to leave the anode, then react in solution and come out of solution as nanoparticles, still floating in the distilled water, and then stay there.

Plate-out is where the silver leaves the anode, goes into solution and then plates out (leaves the solution) onto the cathode as silver crystals or silver oxide, neither of which is desirable; because the silver is lost to the colloidal silver solution and in any case the particles are far too big to be useful.

wow great thread
