Figure 15.

(1) Schematic illustration of the formation of cyclodextrin-modified HA/PLL PEMCs via dissolution of the CaCO₃ template (i), the partial H NMR spectra of cyclodextrin (a), and mixture of cyclodextrin with paclitaxel (b) (ii). (2) SEM images of hollow PEMCs (A,B) and confocal images of PEMCs (C) with corresponding fluorescence profile. (D) The fluorescence arises from the complexation of Oregon-green labelled paclitaxel with the cyclodextrin the PEMC shell.
