Femto-second laser tweezing Example of femto-second pulsed laser “tweezing” where one Fluo-3 AM loaded GH3 pituitary cell is captured using a counter-propagated focused femto-second pulsed laser and then drawn towards another cell. Imaged with a Perkin-Elmer UltraView real-time confocal microscope. |

Real-time confocal imaging with femto-second laser point targeting. Point targeting using a counter propagated objective and a femto-second pulsed laser induces a calcium ion wave in this Fluo-3 AM loaded COS cell. Imaged with a Perkin-Elmer UltraView real-time confocal microscope. Day D, Cranfield C.G., and Gu M. (2006).
