An apt modification: A simple and effective way to modify the cell surface with target-specific ligands, such as DNA aptamers, while minimizing the effects on the modified cells has been developed. After incubating with lipo-aptamer probes, immune cells (red, see scheme) recognize and kill cancer cells (blue) in the cell mixture.
