Why doesn't a negative stain colorize the cells in the smear?

Question

Accepted Answer

∻Answer∻ ⚹ Negative stains do not colorize the cells because they are repelled by the negatively charged cell surfaces. ⚹ ∻Solution∻ ‖ a ⋮ Charge repulsion: The negative stain carries a negative charge which is repelled by the negatively charged components of the bacterial cell surface. ‖ ‖ b ⋮ Background staining: Instead of staining the cells, the dye stains the background, which makes the cells visible as clear areas against a dark background. ‖ ∻Key Concept∻ ⚹ Negative staining technique ⚹ ∻Explanation∻ ⚹ Negative staining relies on the repulsion between the negatively charged dye and the bacterial cell surface to leave cells unstained while coloring the background. ⚹◊What is the principle behind negative staining in microscopy?⍭ Generate me a similar question◊
