Colorized scanning electron micrograph of methicillin resistant staphylococcus aureus (MRSA) bacteria on the surface of a wound dressing.
Specimen was fixed with glutaraldehyde and dehydrated through an ethanol series. It was coated with 5nm gold-palladium and imaged at ultra high resolution (semi-immersion optics). The image was collected on a FEI Nova NanoSEM Family with the following imaging parameters: Magnification: 18,501 x, Horizontal Field Width: 16.1 microns, Vacuum: High vacuum (approx 10 e-06 Torr), Voltage: 5kV, Detector: TLD, Spot: 1.5 nA, and Working Distance: 4.3 mm
