The next image to the right (c) we are looking at nanoparticles with a low amount of the silver (thats the 1000 gold/1 silver ratio), these particles also did NOT kill the bacteria, hmm.
so they need a lot of silver then? hmmm.. just resort to a more affordable band aid and just spread calendula cream on the wound
It's not actually all that much metal no.
They used This Kit to apply silver to the gold nano particles.
I see. costly band aid?
Dunno yet :)
