Differential dynamic microscopy

Differential Dynamic Microscopy (DDM) is a powerful microscopy technique that can be used to measure tiny changes in the movement of molecules in a sample. It works by shooting a laser at a microscope slide with a sample on it. This laser causes the molecules to move in tiny ways that can be seen using a special type of camera. By using computers, the movements of the molecules can be tracked over time and measured to create a picture of how the molecules are behaving. This can be helpful to scientists and doctors because it can tell them more about a sample and the molecules it contains.
