A novel zwitterionic pendant copolymer poly(2-(methacryloyloxy)ethyl phosphorylcholine)-co-poly(2-(methacryloyloxy)ethyl adamantane-1-carboxylate) (poly(MPC-co-Ada)) is synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. The pendant adamantane guest molecules and doxorubicin (DOX) decorated β-cyclodextrins (DOX-hyd-CD) can form inclusion complexation through host-guest...
Miniemulsion reversible addition-fragmentation chain transfer (RAFT) polymerization was used to synthesize biomimetic poly (2-methacryloyloxyethyl phosphorylcholine)-b-Poly (n-butyl methacrylate) (PMPC-b-PBMA) nanoparticles which were used as nanocarriers to encapsulate theranostic IR-780 molecules. IR-780 endowed the PMPC-b-PBMA nanoparticles with dual functions including tumor near-infrared (NIR)...
Biomimic hyaluronic acid (HA) prodrug micelles with pH and reduction responsiveness were prepared by chemical graft of phosphorylcholine and doxorubicin (DOX) to the backbone of HA. DOX was conjugated to HA by pH-sensitive hydrazone bonds which could be hydrolyzed under acidic conditions and thus resulted in controlled release of DOX. Besides, the HA prodrug micelles were cross-linked via reduction-responsive...
A novel amphiphilic photo-degradable hyperbranched polymer was reported at the first time. The hyperbranched o-nitrobenzyl containing poly(amino ester)s (HPAE) were prepared by one-pot Michael addition polymerization. The photo-induced degradation of hyperbranched poly(amino ester)s was confirmed by gel permeation chromatography (GPC) and UV-vis spectra. Bioinspired phosphorylcholine grafted HPAE...
Reversibly light-responsive and biocompatible micelles with an appropriate size were constructed from an amphiphilic spiropyran-containing hyperbranched polyphosphate (denoted as HPHEEP-SP). The polymer was conveniently synthesized based on the modification of a biodegradable hyperbranched polyphosphate with carboxyl-containing spiropyran molecules. HPHEEP-SP can self-assemble to biocompatible micelles...
Particle-assisted fabrication of honeycomb-structured hybrid films was carried out by employing particles as stabilizers in the breath figures (BF) method. Such a procedure tested the possibility of the combination of Pickering emulsions and breath figures, which are two classical self-assembly processes. Regularly patterned porous polystyrene film with particles decorating the inside walls of the...
Phenylboronic acid-containing thermo-responsive block copolymer, poly(ethylene oxide)-b-poly(methoxydi(ethylene glycol) methacrylate-co- aminophenylboronic acid ethyl methacrylate) (PEO-b-P(DEGMMA-co-PBAMA)), was employed to investigate the multiple micellization and dissociation transitions. The unique sugar- and pH-responsive properties of phenylboronic acid were interesting to provide two parallel...
Poly(butanedioic acid, 1-[3-[(2-methyl-1-oxo-2-propen-1-yl)oxy]propyl] ester)-b-poly(methoxydi(ethylene glycol) methacrylate-co-4-methyl-[7-(methacryloyl)oxyethyloxy] coumarin) (PSPMA-b-P(DEGMMA-co-CMA)) block copolymer was synthesized via atom transfer radical polymerization (ATRP). The temperature and pH responsive micellization behaviors of PSPMA-b-P(DEGMMA-co-CMA) were investigated to obtain P(DEGMMA-co-CMA)-core...
A novel hydroxyl-capped comb-like poly[poly(ethylene glycol) methacrylate] (PPEGMA) was prepared via atom transfer radical polymerization (ATRP) of α-methylacryloyl-ω-hydroxyl-poly(ethylene glycol) at ambient temperature. The polymerization kinetics of the block copolymer was studied by gel permeation chromatography (GPC) and 1 H NMR. It is of interest to find the well-defined comb-like PEG...
Crystallization and solid state structure of a poly(styrene)-graft-poly(ethylene oxide) (PS-g-PEO) graft copolymer with crystallizable side chains were studied using simultaneous small angle X-ray scattering/wide angle X-ray scattering/differential scanning calorimetry (SAXS/WAXS/DSC). It is found that the glass transition temperature (T g ) of PS main chain is remarkably higher than that...
The adsorption of plasma proteins (fibrinogen and albumin) from buffer onto polystyrene-graft-(stearyl-poly(ethylene oxide)) (PS-g-SPEO) was investigated by radioiodine labeling of proteins using the iodine monochloride method. The molecular mobility of poly(ethylene oxide) grafts was determined by ESR spectroscopy, and the effects of PEO mobility on the ability of PS-g-SPEO to resist the non-specific...
