GNRH1 and ovarian cancer: Li et al., designed NIR-II Pdots based on NIR-II emitting AIEgens triphenylamine-benzo [1,2-c:4,5-c’]bis([1,2,5]thiadiazole) (BBTD) and amphiphilic polymer PS-PEG to further obtain NIR-II Pdots-GnRH after modification with ovarian-cancer-targeting peptide GnRH for ovarian cancer metastasis detection in vivo (Figure 6a) [57].
