Patent number: 9983115Abstract: A particle detection system with a detection mechanism that includes detectors positioned to detect two different ranges of fluorescence produced by particles in the fluid in a flow chamber. Each of the detectors is arranged to generating a trigger signal whenever fluorescence is detected. The system and related method enhance the accuracy and sensitivity of blue-green algae monitoring by utilizing imaging flow cytometry combined with particle analysis and the measurement of the ratio of each particle's phycocyanin to chlorophyll b detected by using the two detectors configured for detection of two different fluorescence ranges, one associated with the phycocyanin and the other associated with the chlorophyll b. Captured images are be used in comparison to known images of a library of images using a support vector machine classifier.Type: GrantFiled: September 21, 2015Date of Patent: May 29, 2018Assignee: Fluid Imaging Technologies, Inc.Inventors: Christian K.

Publication number: 20120002029Abstract: An imaging flow cytometry system and method which includes a flow chamber, tracking mirror, microscope and imaging optics, image capturing system, device to regulate fluid flow through the chamber, and backlighting generator. The tracking mirror moves at a rate matched to the particle velocity in the flow chamber so as to enhance the sample flow rates possible with the system while maintaining clear and accurate imaging. The backlighting generator passes through the flow chamber and the objective before being focused on the image capturing system. Detected scatter events initiate tracking by the mirror, resulting in imaging with reduced motion blur even at high rates of flow.Type: ApplicationFiled: June 30, 2010Publication date: January 5, 2012Applicant: FLUID IMAGING TECHNOLOGIES, INC.Inventors: Christian K.

Patent number: 5808113Abstract: The invention relates to a process for converting Taxol A, B and C to Taxol primary amine which can then be easily and efficiently converted to Taxol A or docetaxel, thereby significantly increasing the yield of these products from biomass. The method includes the removal of the amide from the side-chain with Schwartz's reagent to form an imine, followed by the hydrolysis of the imine to the primary amine. The primary amine can then be converted to Taxol A or docetaxel. New Taxol imine compounds and primary amine salts have been formed by this process.Type: GrantFiled: May 7, 1997Date of Patent: September 15, 1998Assignee: Hauser, Inc.Inventors: Christopher K.
