(a) Geometric mean fluorescence intensities (GMFI) of the CSCs and non-CSCs after incubation with SV119-PEG-AuNCs with different densities of SV119 for 3 h. respectively. (b) Uptakes of AuNCs by the CSCs and non-CSCs after incubation for 3 h, where the AuNCs had different coverage densities of SV119 on the surface. The CSCs (ALDHhi population) and MDA-MB-435 non-CSCs (ALDHlow population) derived from the mammospheres were labeled using the ALDEFLUOR kit and separately collected using the BD FACSAria III cell sorter. * indicates p < 0.05.
