Nanosilver is most attractive for its bactericidal properties in modern textiles, food packaging,
and biomedical applications. Concerns, however, about released Ag+ ions during
dispersion of nanosilver in liquids have limited its broad use. Here, nanosilver supported on
nanostructured silica is made with closely controlled Ag size both by dry (flame aerosol) and
by wet chemistry (impregnation) processes without any surface functionalization that could
interfere with its ion release. It is characterized by electron microscopy, atomic absorption …
