Quantum dots (QDs) can be targeted with high specificity using the described techniques. The Tz-QDs were targeted to PANC-1 cells labeled with TCO-modified, AF488 fluorescent antibodies to CK and Ki-67 as in Figure 2. Merged images demonstrate strong colocalization between the positive signals, confirming that QDs are targeted with high specificity to the intended target. The scale bar in (i) represents 10 μm.
