Abstract
In this work, a comparative study using atomic force microscopy (AFM) and field emission-scanning electron microscopy (FESEM) has been carried out to assess the morphology of single cell Escherichia coli bacteria (E-coli). E-coli bacteria are a major concern for public health. Attention was focused on the certain strains of E-coli bacteria, because some strains can be toxic and cause food poisoning. The E-coli bacteria have attracted much research interest because this bacterium is easily to get, cheap and rapid reproductively. Imaging of E-coli recently, was improved by using high resolution microscopy. Current techniques for detection such as, AFM and FESEM has attracted great interest and emerging as a potentially powerful whole-organism fingerprinting tool for the rapid identification of bacteria. The obtained results of AFM and FESEM techniques have been compared to show the image quality of single cell E-coli.
