摘要：Apparatus and methods for measuring the fluorescence of large multi-cellularorganisms in a sample of liquid includes a pumping mechanism, a fluorescence measuring
device, a method of analyzing the measurements, and optionally, a sorting mechanism.The pumping mechanism transfers large multi-cellular organisms from a reservoirthrough a fluorescence-measuring device causing minimum physical damage and/orstress. The pressure differential driving the organisms from a sample container/reservoirthrough the measuring device can be derived from gravity, air pressure, or liquidpressure, or some combination of the three. The fluorescence can be measured in acytometer using a light detector or imager. Generally the detection element will includea filter, isolating the wavelength of fluorescent emission. The illumination may beprovided by a laser or by an LED, combined with the use of dichroic mirrors to allowmultiple wavelength simultaneous illumination. In addition, an LED will typically be usedwith a filter to isolate the optimum excitation wavelength while blocking
scattered/reflected LED light from the detection element (but not the fluorescence).
