Fully supramolecular dendrosomes (FSD) as bi-phase drug delivery systems are reported in this work. For preparation of FSD, amphiphilic linear-dendritic supramolecular systems (ALDSS) have been synthesized by host-guest interactions between hyperbranched polyglycerol having β-cyclodextrin core and bi-chain polycaprolactone (BPCL) with a fluorescine focal point. Self-assembly of ALDSS in aqueous solutions led to FSD. They were able to encapsulate paclitaxel with a high loading capacity. The dendrosome-based drug delivery systems were highly sensitive to pH and temperature. They were stable at 20–37 °C and pH7–8, but dissociated and released drug at temperatures lower than 20 °C or higher than 37 °C and pH lower than 7 quickly. Dissociation of FSD building blocks by temperature or pH resulted in inclusion complexes between the released drugs and polyglycerol as the secondary drug delivery system.
