Abstract
This disclosure describes a composition which can provide real-time feedback during medical device cleaning or reprocessing. The composition can be used to monitor the amount of biological material cleaned from medical devices and to determine when cleaning is complete. The disclosure also relates to a method of cleaning, or assessing the cleanliness of, a medical device such as an endoscope. Cleanliness can be assessed by contacting the medical device with the composition, shining an excitation light on the composition, and measuring intensity of resulting fluorescence over time.
