Fig. 3. (a) Bioluminescence spectrum (blue line) of CTZ catalyzed by His–RLuc–GB1, and absorption (red dotted line) and emission spectrum (red solid line) of CdSeTe/CdS QDs in PBS. (b) Bioluminescence spectra for the mixture of QD and RLuc–GB1 protein (QD/RLuc–GB1), and the mixture of QD and His–RLuc–GB1 protein (QD/His–RLuc–GB1) in the presence of CTZ. The molar ratio of QD/fused protein was 0.1.
