Total cell density measurement by the Dencytee sensor is based on optical density, commonly known as the turbidity of a suspension at near-infrared (NIR) wavelengths. All particles and molecules that scatter the NIR light will be detected. This optical density signal can be correlated to the total cell density measured by different offline measurement techniques.
