A facile and green reversed-phase microemulsion co-precipitation method has been developed for fabrication of CaCO3-based composite nanocarriers (NCs) with hyaluronic acid (HA) coatings for oral delivery of insulin. The cell viability of resultant CaCO3-based composite NCs against HT-29 cells was analyzed with different concentration. The chemical stability of loaded insulin against digestive enzyme was established in presence of simulated gastric fluid (SGF) containing pepsin. The uptake behavior of HT-29 cells was evaluated by confocal laser scanning microscope (CLSM). After oral administration to the diabetic rats, an effective hypoglycemic effect was obtained compared with subcutaneous injection of insulin. © 2016 Elsevier B.V.

Dual photo- and pH-responsive polymeric vesicles are constructed from a host-guest complex between a water-soluble pillar[6]arene and an azobenzene ended functionalized poly(ε-caprolactone). Reversible morphological transitions between vesicles and solid aggregates are achieved upon repeated UV stimulus and pH stimulus. Moreover, the polymeric vesicles present excellent cytocompatibility toward HepG2 cells and can be further applied for controlled release of a hydrophilic model drug, DOX•HCl. © 2017 Wiley Periodicals, Inc.

A series of chromophores J1-J4 have been synthesized based on julolidine donors modified with different rigid steric hindrance groups. Compared with the chromophore (J1) without the isolation group, chromophores J2, J3 and J4 show better stability. Structural analysis and photophysical property measurements were carried out to compare the molecular mobility and steric hindrance effect of the different donor-modified chromophores. All of these chromophores with isolation groups showed superb thermal stabilities with high thermal decomposition temperatures above 250 °C. Furthermore, with rigid steric hindrance, chromophores J3 and J4 showed more enhanced thermal stabilities with thermal decomposition temperatures of 269 °C and 275 °C, respectively. Density functional theory was used to calculate the hyperpolarizability (β), and the high molecular hyperpolarizability of these chromophores can be effectively translated into large electro-optic coefficients. The electro-optic coefficients of poled films containing 20 wt% of these new chromophores doped in amorphous polycarbonate were 127, 266 and 209 pm V-1 at 1310 nm for chromophores J1-J3, respectively, while the film containing chromophore J4 showed the largest r33 value of only 97 pm V-1 at 25 wt%. These results indicated that the introduced isolation group can reduce intermolecular electrostatic interactions, thus enhancing the macroscopic electro-optic activity, while the size of the isolation group should be suitable. © 2017 the Owner Societies.

CuO/TiO 2 nanocrystals grown on graphene (CuO/TiO 2-GR) were prepared by a simple hydrothermal method using Cu(CH 3COO) 2·H 2O and (NH 4) 2TiF 6 as precursors and graphene oxide (GO) as templates. The asprepared composites were characterizated by TEM, XRD, FT-IR to determine composition and phase purity. The photocatalytic activity of the samples was evaluated by photo-degradation of methylene blue (MB) aqueous solution under UV and visible light illumination. This work may provide new insights into preparing other inorganic graphene-based composites. © Indian Academy of Sciences.

The multi-sensitive micelles were prepared through a photoinitiated polymerization and self-assembly route using 2-ketobutyric acid (2-KBA) as effective water-soluble photoinitiator and emulsifier. The drug release behaviors were investigated under different glucose concentration, pH and temperature conditions. This work provides a new platform for development drug delivery vehicles with reducing possible utilization of organic solvents and initiators and surfactants. © 2014 Elsevier Ltd.

Au nanoparticles were attached to the surface of polydopamine (PDA) macrospheres by an in situ reduction reaction between PDA and HAuCl4. 4-Mercaptophenyl boronic acid (MPBA) was then modified to form Au-PDA composite particles via a strong Au-S interaction. The resultant MPBA-Au-PDA particles were used in a non-enzyme amperometric glucose sensor. This journal is © the Partner Organisations 2014.

A simple electrochemical biosensor was developed based on graphitic carbon nitride polymers (g-CN) modified glass carbon electrode (g-CN/GCE). The modified electrode displayed the electrochemical sensitive to dopamine (DA) and showed a good linear and broad response to detect of DA. The inorganic ions had no effect on detecting of DA as well. The decreasing of electrochemical activity was only about 10% after exposure in PBS solution for 15 days which showed excellent stability and reproducibility. It is suggested that the g-CN biosensors have promising application for DA analysis. © 2015 Elsevier Ltd. All rights reserved.

Electrospun carbon nanofiber composites (ZnCo2O4/Ag-GO-CNFs) coated with 3D urchin-like ZnCo2O4 nanosheets to form a shish-kebab structure have been prepared using a combination of electrospinning, carbonization and hydrothermal treatments. The composition and microstructure of ZnCo2O4/Ag-GO-CNFs were investigated using field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis. Interestingly, ZnCo2O4/Ag-GO-CNFs provided a new style of electrode materials and exhibited an excellent specific capacity of 459.48 mA h g-1 at 20 mV s-1. Notably, the specific capacity of ZnCo2O4/Ag-GO-CNFs also exhibited a remarkable cycling stability (96.0% retention after 9000 cycles), which holds great promise for practical applications in energy storage devices as a carbon-based electrode material. © The Royal Society of Chemistry 2016.

The Mn-doped ZrO2/TiO2 nanostructured photocatalysts had been prepared by the simple hydrothermal method. The morphologies and structures of the as-prepared photo-catalyst were characterized by transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy, and electron paramagnetic resonance. The resultant nanostructured photocatalysts exhibited high photocatalytic activity under ultraviolet (UV) light irradiation, attributing to the improvement of the photo-absorption property and the separation efficiency of photo-generated electrons and holes. The hydroxyl radicals (•OH), superoxide radical (•O2 -), and holes (h+) are the main active species in aqueous solution under UV light irradiation. © Materials Research Society 2015.
