| Abstract: | Objective To study the effect of peptide-conjugated near-infrared quantum dots(QDs) on growth, invasion and metastasis of human buccal squamous cell carcinoma cell line(BcaCD885 cell).Methods 1)BcaCD885 cells were labeled by cell-penetrating peptide-conjugated QDs with a maximum emission wavelength of 800 nm(QD800),then labeling efficiency was detected by flow cytometry,and laser-scanning confocal microscope was used to observe the distribution of QD800 within the cells.2)Different concentrations of QD800 w... |
