Analysis of the interaction between PBA-Au NPs and β-CD-Rluc. a Agarose gel electrophoresis (0.5%); the concentration of β-CD-Rluc is 10 µM. In agarose gel electrophoresis, the samples from left to right are, PBA-Au NPs alone (lane 1), PBA-Au NPs reacted with β-CD-Rluc (lane 2), PBA-Au NPs incubated with Rluc (unmodified Rluc, lane 3) and MUA-Au NPs (lane 4), respectively. b Bioluminescence spectra of β-CD-Rluc responding to the addition of PBA-Au NPs with different molar ratio
