Title: Innovations by David P Marchessault
Introduction
David P Marchessault is an accomplished inventor based in Hopkinton, MA, with a focus on advancements in biotechnological applications. He holds two patents that reflect his innovative contributions to the field of cell viability and bioreactor monitoring.
Latest Patents
One of his latest patents is titled "Fabry Perot interferometry for measuring cell viability." This method involves establishing a Fabry Perot etalon signal within an optical spectroscopic feature, particularly in the near-infrared region. The technique allows for the study of cell viability and protein aggregation by observing changes in the magnitude of the Fourier Transform peaks associated with the etalon contrast. The presence of viable cells and protein aggregates can degrade the etalon contrast, providing valuable insights into cell health and protein behavior.
Another significant patent is the "In-situ probe," a device designed for monitoring bioreactors. This innovative tool enables in-situ analysis without the need to withdraw samples into a separate cell. The device can be inserted into a bioreactor port and features a sample detection region defined by an optical element, such as a lens, and a photodetector. The electrical signals obtained from the photodetector can be directed to an analyzer through a detachable electrical connection, enhancing the efficiency of bioprocess monitoring.
