Thus, we designed a gold nanoplatform (GNPF) that specifically targets ovarian cancer cells, based on gold nanospheres (GNS) carrying miR-145 as the active molecule, conjugated with 5 kDa polyethylene glycol (HS-PEG-NH2) and the FSH33 peptide as a ligand for the FSH receptor specifically expressed in ovarian cells [12]. Here, FSHR is linked to ovarian carcinoma.
