a Synthesis of NMP-BE. b The structures of SAC5A, SC5A and SBE-β-CD. c Competitive fluorescence titration of RhB@SAC5A (0.30/0.50 μM) with NMP-BE (up to 2.9 μM) in PBS (10 mM, pH = 7.4) at 25 °C, λex = 554 nm. d The associated titration curve at λem = 575 nm and fit according to a 1:1 binding stoichiometry. e Fluorescent responses of RhB@SAC5A (10/10 μM) upon the addition of various biologically coexisting species in blood. Data are presented as mean ± SD (n = 3 biologically independent samples). Source data are provided as a Source Data file.
