(a) Linearity of attenuation of calibration vials containing AuNP for each energy bin. R2 = 0.99 for all linearity trends. (b) Spectral response of the detector for calibration vials. Enhancement of attenuation due to K-edge observed in energy bin 4 (75–118 keV). Insets show material decomposed images corresponding to each concentration. (c) and (d) Spectral response of Raji and SKBR3 cells, respectively. Standard errors are shown for spectral response data.
