title: Laser-assisted microinjection into targeted animal cells.
abstract: A pulsed (17 nanoseconds) Nd:YAG laser (1064 nm) was used to inject impermeable dyes (propidium iodide andiodide and merocyanine 540) and a plasmid (pEGFP-N1) encoding green fluorescent protein (GFP) into human breast adenocarcinoma cells (MCF-7). The cell membrane integrity and viability were fully preserved in this laser-assisted transfer.
