How do optical dissolved oxygen sensors work? Optical DO sensors are made of two parts, a sensor spot and a fiber optic reader. The sensor spot is attached to the interior of a cell culture vessel and contains a fluorescent dye suspended in a hydrogel. The sensor spot is the only part of the system that comes in contact with cells or media.
