Abstract
A device for monitoring a bioreactor is designed for in-situ analysis, e.g., by NIR. The device is configured for maintaining a sample detection region in the reactor medium and can include two or more components, at least one of which is fabricated additively. In an example, a light beam propagates along a free space optical path, passes through a thin 3D printed layer and traverses the sample detection region, where it becomes modulated or modified by interactions with analytes present in the bioreactor. The transmitted light reaches and passes through another thin 3D printed layer and is detected by a photodetector, internal to the device. The electrical signal from the photodetector can be directed to an analyzer via electrical connections. The device or a component thereof can be designed for single use applications.
