Single-Cell DNA Transfection (IMAGE) Optica Caption a) A laser scanning microscope image of a cancer cell used in the experiment is shown. The green circles show plasmid-coated particles that have been optically tweezed and inserted into the cell. b) The same cell viewed with a fluorescence microscope is shown. The DNA material inserted into the cell through the transfection process carries a gene that codes for a green fluorescent protein. Here, the cell's green glow means the transfection process was successful. c) Image (b) is superimposed on image (a).
