How do biological dyes work?

Biological dyes, such as carbol fuschion or crystal violet, work by adhering themselves to the cellular membrane of a cell.
A cell membrane is composed of many different molecules and structures, such as proteins, lipids (fats), carbohydrates and phosphates. Each of these is capable of binding to something, and dyes are made such that they bind with one of these molecules.
Some dyes are created such that they will bind to the phopholipid bilayer that is present in all cell membranes. Generally such dyes serve the purpose of making a cell viewable under a microscope.
Other dyes are cell specific, only binding to proteins or carbohydrates that are specific to certain cells. A great example of this is a Gram Stain, which is used to determine the general type of bacteria, known as Gram Positive or Gram Negative.
Hopes this helps!
