No, really. I can't seem to find anything that properly explains this concept. What are nanoparticles? Are they charged metal ions held together by bridging ligands, or...?

• Nanoparticles can be made of pretty much anything, like ordinary particles. – Ivan Neretin Jan 30 at 11:03
• Nano- implies an average size of $10^{-9} m$ – Buck Thorn Jan 30 at 11:34
• I was referring more specifically to colloidal metals (i.e. silver, gold). What are those made of? – FlyingFalcon Jan 30 at 11:36
• You are still asking a wrong question. The literal answer is bound to be useless. Particles of colloidal metals are made of metals; nothing more general can be said. – Ivan Neretin Jan 30 at 11:49
