Applied physics produces and analyzes the images.
Cut and Paste Let's start with luciferase , the enzyme that makes some insects, jellyfish, and bacteria glow. When it is present, it reacts with a substrate to produce light. This change in the genetic structure of cells, microorganisms, and animals is a process called gene splicing. Researchers can study a range of diseases with tagged cells, including tumor cells to study cancer or bacteria cells to study infection. The more cells there are, the brighter the light will be.
