  • Particle manipulation system with camera/classifier confirmation and deep learning algorithm
    Patent number: 11898954
    Abstract: A MEMS-based particle manipulation system which uses a particle manipulation stage and optical confirmation of the manipulation. The optical confirmation may be camera-based, and may be used to assess the effectiveness or accuracy of the particle manipulation stage. In one exemplary embodiment, the particle manipulation stage is a microfabricated, fluid valve, which sorts a target particle from non-target particles in a fluid stream. The optical confirmation stage is disposed in the microfabricated fluid channels at the input and output of the microfabricated sorting valve. Deep learning techniques are brought to bear on the camera output to increase speed, accuracy and reliability.
    Type: Grant

In one exemplary embodiment, the particle manipulation stage is a microfabricated, fluid valve, which sorts a target particle from non-target particles in a fluid stream. The optical confirmation stage is disposed in the microfabricated fluid channels at the input and output of the microfabricated sorting valve. The laser interrogation regions may be used to assess the effectiveness or accuracy of the sorting, and to control or adjust sort parameters during the sorting process.

  • Methods of measuring fluorescence lifetime using a flow cytometer
    Patent number: 9632030
    Abstract: A method for determining fluorescent lifetime of a fluorescent particle in a flow cytometer comprising calculating a point on a digitized scatter waveform and a corresponding point on a digitized fluorescence waveform using the same method and calculating the time delay if any between the calculated point on the digitized scatter waveform and the calculated point on the fluorescent waveform to determine the fluorescent lifetime of the fluorescent particle with digitized data collected from a flow cytometer having an unmodulated light source.
