Abstract An anhydrous glycerol colloid containing nano-silver was synthesized for the first time with heating and stirring method by using silver nitrate (AgNO₃) as silver source, anhydrous glycerol as reducing agent and dispersion medium, and PVP-K30 as a stabilizer and template agent. The resulted colloid and the colloidal silver were characterized by ultraviolet-visible spectroscopy, X-ray powder diffraction and transmission electron microscopy. The effects of the amount of AgNO₃ and reaction time to the colloid and the morphology of metallic silver were explored. The results showed that the stable silver glycerol colloid can be synthesized under the following conditions: m(glycerol)∶m(AgNO₃)∶m(PVP-K30) = 200∶(0.5-1.5)∶5, reaction temperature 110 ℃, reaction time 0.5-3 h. The silver particles in the suspension are subglobose and well dispersed, and their particle sizes are in nano-level. The antibacterial property of the silver colloid was investigated using Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. The result showed that the anhydrous glycerol colloid containing nano-silver has good antibacterial property to the four target bacteria, and displays the strongest antibacterial effect on Bacillus subtilis. On the other hand, it was proved that the silver particles with smaller sizes possess better antibacterial property.
