“…Furthermore, existing nanobiology technologies should be fully utilized, through finding specific surface markers of targeting BCSCs, to locate and eliminate BCSCs accurately. Recently, biologically and chemically synthesized gold nanoparticles (AuNPs) (Virmani et al, 2019), silver nanoparticles (AgNPs) (Muthupandian et al, 2019) and selenium nanoparticles (SeNPs) (Vahidi et al, 2020) have attracted significant attention for their anticancer effects against cancers such as lung cancer, colorectal Cancer (Barabadi et al, 2020a), cervical cancer (Barabadi et al, 2020b) and prostate cancer (Barabadi et al, 2019a). Fortunately, AuNPs (Barabadi et al, 2019b) and AgNPs (Saravanan et al, 2020) have also been reported to play an important role in the treatment of BC.…”
