It is better to synthesize nanoparticles of Ag from PVP + AgNO3. It would be better to stabilize the nanoparticles. See attached file.
Best regards.
Thank you very much for that link. It provided interesting facts regarding what I am ultimately trying to find out which is the percentages of PVP and AgNP in a preparation, and the effects on the AgNP as an antimicrobial. What I gather from the research of the link you posted, if the concentration of PVP gets too high, the AgNP can perhaps no longer have as much anti-microbial effect because the Ag particles get "tangled" amid too dense of a concentration of PVP. Concluding from the study you linked to, if one were to get a preparation of AgNP stabilized with a PVP coating for the purpose of antimicrobial effects, one would look for a PVP concentration of between 1% and 10% in the preparation but no more, being that a higher concentration of PVP would possibly interfere with the AgNP effect on bacteria. Would you say that conclusion is correct?
Yes, PVP will interfere with the bactericidal action of Ag. We are engaged in similar work. See our work in my profile.
Regards.
