Injecting Membrane Impermeable Substances into Single Cells
The ability to load membrane impermeable substances into cells is of great interest to cell biologists. Optical transfection is one of the few technologies that allows single cells to easily be transfected, without affecting neighbouring cells. The image shows six cells, three of which were transfected with a plasmid encoding for green fluorescent protein (green & blue cells), and three of which that were not. Cells are co-stained with the blue nuclear dye, DAPI, so only the nuclei of untransfected cells are visible. Early transfection work employed a Ti:Sapphire femtosecond pulsed laser using a standard Gaussian beam profile. More recent work has employed the use of a Bessel Beam profile, obviating the need for exact focussing and opening the possibility of a “point-and-shoot” device for the biological community. Current work is ongoing to apply this technology to an axicon tipped fibre, thereby freeing the operator from bulky objectives.
