Multiplexed Amplitude Modulation Photometer And Performing Multiplexed Amplitude Modulation Photometry
Patent Number: 12,072,277
Estimating abundance of cancer antigen on individual cells in a blood sample, for example, is difficult due unknown uncertainties of each measurement, as it has previously been impossible to repeat measurements on single particles in flow. Multiple measurements of particles (such as cells) in flow permit uncertainty quantification (thus improving quantification and classification) and measurements of dynamic processes, but collecting multiple measurements requires additional detectors, which makes instruments large and expensive.
Invention
The invention - a multiplexed amplitude modulation fluorometry, is a method of signal generation, acquisition, and analysis that can simultaneously detect and distinguish fluorophores contained on or in many distinct samples separated in space and/or wavelength.
Commercial Application
Biomedical research, cancer detection, drug development, etc.
Competitive Advantage
Our technique enables multiplexing any number of repeated measurements in time or space to a single detector. The technique reduces or eliminates errors due to misalignment of photodetectors and unknown geometric factors. Moreover, the AC and DC components of any signal carry the same information, so that the method inherently performs repeat measurements at the same location and time. These advances enable reproducibility and reduce complexity of device design (both number of and geometric factors associated with detectors), which are critical to improving the quality and accuracy of biomedical research tools such as flow cytometers.
