The inventive bioprocessing system (and technique) relies on non-invasive optical
chemical sensing technology wherein an optical excitation source excites an optical
chemical sensor. The optical chemical sensor then emits luminescence or absorbs
light which is measured by a detector. The luminescence emitted from the chemical
sensor or the amount of light absorbed by the chemical sensor is related to the
concentration of an analyte, such as oxygen. If the luminescence emitted changes,
or if the amount of light absorbed changes, then the concentration of the analyte
has changed. Using such a system to measure and adjust multiple parameters at one
time allows one to efficiently and cost-effectively determine optimal conditions
for a given cell type and/or cell environment, for example. By combining cell cultivation
with optical chemical sensing technology, cultivation can be successfully and rapidly
performed, controlled and monitored in small volumes in an automated, parallel
fashion at less expense than current bioprocess techniques.
