GRN and cancer: It is possible to diagnose cancer cells by tumor receptor detection(epidermal growth factor receptor, proepithelin), malfunction detection, location of tumor cells besides intercellular chemical analysis, and finding targeted cells with dendrimer, NT, nanoshells, iron oxide (FeO) NP and QD (Mohanty et al., 2014; Pati et al., 2009; Scott, 2005).
