A student contacted us with a question:
I need to carry out antibacterial activity The sample I have is a nanoparticles which doesn't dissolve in any of the solvents such as water, methanol, DMSO, ethyl acetate etc. In such cases how do I carryout these tests?
I answered him:
To study the bactericidal properties of nanoparticles, for example, silver and copper, they do not need to be dissolved. It is necessary to prepare a dispersed system in an aqueous extract of the leaves of a bactericidal plant or with cationic surfactants to stabilize them (so that the nanoparticles do not settle). Each country has its own testing standards for such drugs. See the method in the article
