Thereby, Nguyen et al. managed to develop PEGylated liposomes in which they included rapamycin and polypyrrole (PPɣ) NPs for the targeted chemo-photothermal therapy of HER2+ breast cancer cells [58], while Amin et al. created Tmab-conjugated liposomes to specifically deliver idarubicin to the same sort of tumor cells [59]. The gene discussed is ERBB2; the disease is breast cancer.
