GQDs inhibit HUVECs cell proliferation in vitro. A GQDs inhibit the proliferation of HUVECs. EdU assay was used to determine cell proliferation. Total cells were stained in blue and proliferating cells were stained in red. B quantitative measurements of the percentage of EdU positive cells. Data was presented as the means ± SD, n = 4 (**P < 0.01; ***P < 0.001)
