Likewise, polymersomes encapsulating plitidepsin and targeted with an anti-EGFR antibody showed greatly increased cytotoxicity and cellular uptake in colorectal cancer cell lines compared to an untargeted polymersome.25 Liposomes targeted with EGFR-binding peptides have also been used to deliver doxorubicin26 and cisplatin27 effectively to cancer cells. Here, EGFR is linked to colorectal cancer.
