It involves staining an organism with crystal violet or methylene blue dye and then observing the organism under a microscope. Gram-positive bacteria have a thick peptidoglycan cell wall.

By designing a novel molecule called a pyrazinacene derivative, the team developed a crystal that shifts its color from greenish-blue to red-violet when exposed to naphthalene, a well-known air ...
