Nigrosin can be used for negative staining of bacteria. The shapes and sizes of the organisms are seen as colour-free outlines against the dark background. An advantage of using this method, rather than regular positive stains like methylene blue or carbol fuchsin, is that prior fixation by heat or alcohol is not needed, so the organisms are seen in more life-like shapes. Furthermore, negative staining with nigrosin can reveal some microorganisms that cannot be stained by regular methods.
