Comparison of the three varieties of nanoroses. (a) DIC and confocal images of the thick knobby and thin round in macrophage culture, with original nanorose (thin knobby) shown in Figs. 3 and 5. (b) Quantitative comparison of luminescence intensity of the three nanoroses, average spectrum from Fig. 7(d). (c) Extinctionspectrum of thin round, thick knobby and thin knobby (original nanoroses). (d) Maximum luminescence from individual experiments in A. M1 firstluminescence peak at 650 to 670 nm, M2 is the second luminescence peak at 745 to 760 nm. .
