Corrigendum to “Multifunctional calcium phosphate nano-contrast agent for combined nuclear, magnetic and near-infrared in vivo imaging” [Biomater. 34 (2013)7143–7157](S0142961213006698)(10.1016/j.biomaterials.2013.05.077)

In Fig. 2a, the NIR image of 0.1% ICG-nCP sample was accidently misplaced with that of 3rd wash supernatant of PEGylated ICG-nCP sample (Fig. 2d). We have corrected Fig. 2 as shown below. In Fig.6b (Inset), the SEM image of RBC treated with calcium phosphate (MF-nCP)nanoparticles was misplaced with that of calcium hydroxyapatite (nHAp)nanoparticles. The corrected Fig. 6 is shown below. Both these corrections have not affected the final conclusions of the paper which was supported by quantitative plots of related assays in Figs. 2b and 6b. Corrected Fig. 2 [Figure presented]Fig. 2. (a)Fluorescence image of ICG-nCP samples doped with increasing concentrations of ICG, (b)graph showing integrated emission intensity from different batches of ICG-nCP samples. Inset: fluorescence spectra of ICG-nCP. Fluorescence image of the supernatants obtained from subsequent washing of ICG-nCP capped with (c)silica, (d)PEG, (e)PEI, (f)graph showing integrated fluorescence emission from ICG that leached out into the supernatants, on subsequent washing of capped ICG-nCP samples. Corrected Fig.6b [Figure presented]Fig. 6. Hemocompatibility analysis of MF-nCP, (a)cell viability analysis of PBMC treated with MF-nCP for an incubation period of 48 h, (b)hemolysis data of different concentrations of MF-nCP treated with whole blood. Inset: SEM image of RBC treated with MF-nCP (200 μg/mL), (c)flow cytometry based platelet activation data showing platelets treated with PBS, ADP and 200 μg/mL MF-nCP.
