GRPR and neoplasm: These studies proved that the DOTA-containing AuNPs functionalized with a BBN thioctic derivative are the most promising ones, allowing for a fast complexation of trivalent radiometals (e.g. 67Ga3+) and showing high in vitro/in vivo stability, along with a favorable cellular internalization in GRPr-positive cells and significant tumor uptake [52,53].
