2.2.5. Scanning electron microscopy
Electron microscopic imaging was performed using a JEOL JSM-7800F
Scanning Electron Microscope (SEM) equipped with Energy Dispersive
Spectroscopy (EDS). The silver particle-containing bacteria were
dropcast on to a cover glass and let dry overnight at room temperature,
and after gold sputtering the immbolised bacteria were imaged using the
electron microscope at an acceleration voltage of 15.0 kV. In addition,
EDS was conducted on the selected areas of the sputtered glass for
elemental analysis.
