Method and apparatus for removing, from a flowing liquid stream containing a suspension of living cells, a subpopulation of unwanted cells having one or more characteristics distinguishing them from the rest of the living cells. The method includes detecting the presence of the unwanted cells, generating signals in response to the presence of the unwanted cells, and providing pulses of laser light, in response to the generated signals, to impinge on and kill the unwanted cells.
