Also disclosed herein is a method of treating and detecting cholangio-cancerous cells from a biological sample of a subject suspected of having cholangiocarcinoma (CCA). The method includes steps of, contacting the biological sample with a magnetic bead pre-coated with the compound of formula (I); detecting a complex formed between the magnetic bead and the biological sample in an immunoassay; and administering to the subject an effective amount of a chemotherapeutic agent to ameliorate symptoms associated with the CCA.
