For example, a metallopolymer micelle with NIR‐controlled HER‐2‐targeting capability was invented for integrated PDT and chemotherapy on HER‐2‐overexpressed cancer.[166] The multifunctional micelle was formed by polymerizing cyclometallated Ir3+ complex possessing non‐emissive 3IL state with lapatinib‐conjugated PEG monoether and then co‐assembling with upconversion NPs. This evidence concerns the gene ERBB2 and cancer.
