Patent number: 11644408Abstract: An optical cell for performing light spectroscopy (including absorbance, fluorescence and scattering measurements) on a liquid sample in microfluidic devices is disclosed. The optical cell comprises an inlaid sheet having an opaque material inlaid in a clear material, and a sensing channel that crosses the clear material and the opaque material provides a fluidic path for the liquid sample and an optical path for probe light. Integral optical windows crossing a clear-opaque material interface permit light coupling into and out of the sensing channel, and thus light transmission through the sensing channel is almost entirely isolated from background light interference. A microfluidic chip comprising one or more optical cells is also disclosed. The optical cells may have different lengths of sensing channels, and may be optically and fluidly coupled. A method of manufacturing an optical cell in a microfluidic chip is also disclosed.Type: GrantFiled: November 10, 2021Date of Patent: May 9, 2023Assignee: DARTMOUTH OCEAN TECHNOLOGIES INC.Inventors: Edward Arthur Luy, Sean Christopher Morgan, Vincent Joseph Sieben
