We have carried out surface and zeta-potential measurements on AgCl AgBr single crystals. As for particle systems we find that, surprisingly previously unnoted, the exhibits pH-dependence, while potential does not. A possible interpretation of these observations is involvement water ions in interfacial equilibria particular, stronger affinity hydroxide ion compared to proton. The pH-dependence can be suppressed at sufficiently high silver concentrations, which agrees with previous where no...

Biocompatible gold nanoparticles (AuNPs) are used in wound healing due to their radical scavenging activity. They shorten time by, for example, improving re-epithelialization and promoting the formation of new connective tissue. Another approach that promotes through cell proliferation while inhibiting bacterial growth is an acidic microenvironment, which can be achieved with acid-forming buffers. Accordingly, a combination these two approaches appears promising focus present study. Here, 18...
