1. A method which provides real-time feedback for a system that destroys an undesired cell, comprising:
detecting a first fluorescence of a cell with a detector with a detection event lasting no more than six microseconds (6 μs);
classifying the cell as an undesired cell or a desired cell based on the detection of the first fluorescence;
destroying the undesired cell with a kill event lasting between ten and fifteen nanoseconds (10-15 ns) if the cell is classified as an undesired cell; and
confirming whether the undesired cell was destroyed by detecting a second fluorescence of the cell during the detection event.
