Fig. 1From: Effect of gadolinium-based nanoparticles on nuclear DNA damage and repair in glioblastoma tumor cellsLocalization of GdBNs-Cy5.5 nanoparticles in U87 cell. a Correlative fluorescence confocal image and transmission light image of U87 cell with internalized GdBNs-Cy5.5 (red) at the end of 16 h-long observation. The scale bar equals to 10 µm. The circles represent the regions of fluorescence spectroscopy measurements, cytoplasm (blue), nucleus (red), and plain medium (green). b Fluorescence emission spectra of the three regionsBack to article page
