photon correlation spectroscopy

Photon Correlation Spectroscopy (PCS) is a technique used to study tiny particles in liquids, such as proteins or polymers. It works by shining a laser light on the sample and analyzing the scattered light that bounces off the particles. As particles move, the scattering changes over time. By measuring these fluctuations, researchers can infer details about the size and movement of the particles. This information helps in understanding various properties of materials, making PCS valuable in fields like biology, chemistry, and materials science.
