Capsules are made of polysaccharides and/or polypeptides that have no net charge. Most dyes used do have a net charge. Therefore, capsules cannot bind to charged dyes and do not stain as a result. Capsules may be revealed by methods such as Maneval's method. This method utilizes negative staining, where the background is stained revealing an unstained structure of interest: the bacterial capsule.
