Directed positioning of micronuclei in Paramecium tetraurelia with laser tweezers: absence of detectible damage after manipulation.

Abstract excerpt

Possible covert damage from the use of the laser optical force trap (laser tweezers) to reposition micronuclei in Paramecium tetraurelia was assessed by measuring proliferation rates and postautogamous survival and mutation rates of cells after laser manipulations. No differences in subsequent da...
