Abstract
The first attempts of bacteria observation started with the use of glass lenses to generate magnified images of specimens. This technique is constrained by the principal limit to the resolution of any optical system. Besides optical microscopy, other imaging techniques emerged to reveal more levels of details. The more the achievable resolution, the more complex the imaging systems, and at the same time, the more potentially cell-killing or DNA-damaging they may become. This article provides a state of the art of nonconventional sensor techniques that have been used in applications related to bacteria imaging, for the purpose of comparing the information they provide and determine their suitability or find out if their combination can yield new results without compromising the ability to keep the cells alive.
