Even cells that become cancerous may differ from their healthy neighbors in only a few subtle ways. A central challenge in the treatment of cancer and many other diseases is being able to spot the right cells while sparing all others.

These target a therapeutic agent only to cells with specific, predetermined combinations of cell surface markers.
