2.2.2. Flow cytometry
Scattering properties of silver-containing bacteria were measured using
a CytoFlex S flow cytometer (Beckman Coulter). The bacterial mixture was
transferred to the sheath fluid with a bacterial concentration of
105 mL-1 for flow cytometry. Next,
with the laser beam passing the bacteria in the fluid, both forward
scattering and side scattering signals of those bacteria were detected
and analysed. In addition, specific concentrations of bacteria in a
solution were measured by flow cytometry.
