Characterization of RBCQDs. (a) TEM image of RBCQDs. (b) The hydrodynamic diameter of RBCQDs is measured by dynamic light scattering. (c) Zeta potential of RBCQDs. (d) Optimal excitation (blue line, λ ex = 435 nm) and emission spectra (red line, λ em = 505 nm) of RBCQDs, Inset images on the right, photographs of RBCQDs under brightfield and 365 nm UV illumination. (e) 3D fluorescence spectra of RBCQDs. Changes in size (f), zeta potential (g) and fluorescence intensity (h) of RBCQDs over time in artificial cerebrospinal fluid (n = 6/group, one-way ANOVA)
