What is colloidal gold?
I would like to ask some questions regarding the uses of Colloidal Gold. Is it the same as colloidal silver? Can it be use as colloidal silver? Some
doctors say that it is used in making the drugs. Is it true? Should it also kept in liquid form as the colloidal silver? If you got any kinds
information about it, then please inform me.

This seems like quackery promotion with a side of spamming but since colloids are interesting I leave the thread open for now, having removed the
commercial link.

Re: Drugs. It's a decent drug carrier. Don't know anything about manufacture.
I also recall one of my lecturers saying it can be used in some way to aid tumour detection.
“If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found
the object of his search.
I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.”

I know a professor who was seeking to functionalize colloidal gold particles with carbohydrate ligands. The logic was that these ligands would
specifically bind to certain receptors on cancerous cells. Once bound, these cancerous cells would incorporate the colloidal gold and be killed.
Cool idea. Of course, there were a host of complications with this idea (mostly that cancerous cells are quite unpredictable in their
structure/mechanisms of action) so it remains to be seen if this will have practical application!

Purple of Cassius is said to be colloidal gold.
I've done it with HEPES (that made nanoparticles, pretty purple solution) and also with ascorbic acid (this gives you a larger particle that is red in
solution)
Neither flask nor beaker.
