Abstract
To construct pH/temperature dual sensitive micelles as novel drug delivery carriers, the synthesis of two diblock copolymers mPEG113-PMCC9-(PMCC-DBO)27 and mPEG43-PMCC25-(PMCC-DHO)15 based on mPEG and polycarbonate modified by acid and liquid crystal groups is described. In aqueous solution, mPEG113-PMCC9-(PMCC-DBO)27 and mPEG43-PMCC25-(PMCC-DHO)15 could self-assemble to form nanospheres and vesicles at very low critical micelle concentration, respectively. Both nanospheres and vesicles were less than 100 nm in diameter and demonstrated high loading capacity of doxorubicin (DOX) through ionic interaction between the free carboxyl groups in PMCC segments and the amine groups in DOX. In vitro release studies indicated that the two copolymer micelles were capable of pH/temperature-triggered release of doxorubicin and without a significant initial burst release. Furthermore, MTT assays showed that the blank copolymer micelles were nontoxic, while the drug-loaded micelles exhibited potent cytotoxic activity towards HeLa cells. These pH/temperature responsive copolymer micelles provided a new strategy for constructing stimuli-responsive drug delivery carriers in chemotherapy.

Abstract
Norbornenyl cyclic elastin-like peptides were polymerized via ring opening metathesis polymerization (ROMP) to generate thermally responsive brush polymers. The thermally-responsive nature of the materials could be attenuated by the addition of a proteolytic enzyme that causes the cyclic peptide side chains to be linearized.

Abstract
We demonstrate a new, scalable, simple, and generally applicable two-step method to prepare hollow colloidosomes. First, a high volume fraction oil-in-water emulsion was prepared. The oil phase consisted of CH2Cl2 containing a hydrophobic structural polymer, such as polycaprolactone (PCL) or polystyrene (PS), which was fed into the water phase. The water phase contained poly(vinylalcohol), poly(N-isopropylacrylamide), or a range of cationic graft copolymer surfactants. The emulsion was rotary evaporated to rapidly remove CH2Cl2. This caused precipitation of PCL or PS particles which became kinetically trapped at the periphery of the droplets and formed the shell of the hollow colloidosomes. Interestingly, the PCL colloidosomes were birefringent. The colloidosome yield increased and the polydispersity decreased when the preparation scale was increased. One example colloidosome system consisted of hollow PCL colloidosomes stabilized by PVA. This system should have potential biomaterial applications due to the known biocompatibility of PCL and PVA.
