A Dh and PDI of PHEMA-g- (PCL-BM: CD-star-PMAA-b-PNIPAM) micellar solutions at various weight ratios of BM moieties to β-CD. The ultimate polymer concentration of each sample was set at 0.2 mg/ml. B Intensity ratio I384/I373 from pyrene excitation as a function of the concentration of the PHEMA-g-(PCL-BM: CD-star-PMAA-b-PNIPAM) micelles. C 2D-NOESY NMR spectra of the PHEMA-g-(PCL-BM: CD-star-PMAA-b-PNIPAM) inclusion complex in DMSO-d6 as solvent at a guest/host weight ratio of 1:3 (400 MHz). D FTIR spectra of PHEMA-g-(PCL-BM) (guest), CD-star-PMAA-b-PNIPAM (Host), and PHEMA-g-(PCL-BM): CD-star-PMAA-b-PNIPAM (micelle). E Fluorescence emission spectra of PHEMA-g-(PCL-BM) in DMSO/PBS solutions with different CD-star-PMAA-b-PNIPAM concentrations (λex = 297 nm). F 3D and 2D atomic force microscopy (AFM) images of PHEMA-g-(PCL-BM), G PHEMA-g-(PCL-BM: CD-star-PMAA-b-PNIPAM) inclusion complex
