Bacteria on a pin. Coloured scanning electron micrograph (SEM) of bacteria (orange) on the tip of a pin. Although considered sharp and smooth on a human scale,it can be seen that the surface of the pin is rough and the tip is blunt on the scale of a bacterium. Magnification: x1600 when printed 10cm high. In terms of microns (thousandths of a millimetre),the tip of the pin is some 30 microns across,and the bacteria are about 5 microns long | |
