Abstract:
1. A device for analyzing particles in a sample; said device comprising: an at least partially transparent container for holding said sample containing said particles, said container having a center; an optical source for generating excitation light that is provided to said sample, thereby causing at least a portion of said particles to generate fluorescence; a means for collecting fluorescence from an observation volume positioned within said container; a means for moving said container, thereby transporting at least a portion of said particles through said observation volume, wherein said means for moving said container simultaneously rotates said container about a rotational axis passing through the center of said container and vertically inverts said container; a photodetector in optical communication with said means for collecting fluorescence for receiving and measuring intensities of at least a portion of said fluorescence from said observation volume; thereby generating a temporal profile of said fluorescence; and a processor having a pattern recognition algorithm for receiving and analyzing said temporal profile generated by said photodetector.
