Cell specificity of BIM-I-loaded NPs may be tuned by attaching the near-infrared dye DY-635, since it is a fluorescent ligand to organic anion transport pumps (OATPs) OATP1B1 and OATP1B3, which are expressed by hepatocytes and various types of cancers [28,29]. The gene discussed is SLCO1B3; the disease is cancer.
