A facile method has been developed to grow MnO2 nanoparticles on hybrid carbon nanofibers (MnO2/HCNFs) for flexible supercapacitors (SCs). The hybrid carbon nanofibers (HCNFs) could be serviced as a buffer layer to improve the conductivity of MnO2 and enhance the interface contact between MnO2 and carbon nanofibers. The flexible SCs based on MnO2/HCNFs hybrid structure exhibited good electrochemical performance, extraordinary flexibility and superior cycle lifetime. Specific capacitance of the flexible SCs was 803.6 mAh g−1 at the scan rate of 20 mV s−1. Maximum specific energy (power) density was 20.1 Wh/kg (230.4 W/kg). © 2017 Elsevier B.V.

In this paper, hierarchical nanostructures of BiOBr/AgBr on electrospun carbon nanofibers (CNFs) were prepared by combination of electrospinning and carbonization. Compared with the smooth surface of CNFs, the rough surface with hierarchical nanostructures of BiOBr/AgBr can be obtained by adding the certain amount of BiOBr/AgBr precursors into the spinning solution. The as-prepared composite CNFs exhibited highly photocatalytic activities for degradation of rhodamine-B and reduction of p-nitrophenol under the visible-light irradiation and at room temperature. Furthermore, the as-prepared composite CNFs showed the favor separation, recovery, and cyclic utilization properties. © Materials Research Society 2016.

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.

Crystalline/ionic liquid crystalline block copolymers (BCPs) with various compositions have been successfully prepared by sequential reactions. The effect of corona liquid crystalline order on self-assembly of BCPs in selective solvent is investigated in detail. It is found that two-dimensional single crystals with well-developed shapes are formed when the liquid crystalline order is present. By contrast, ill-developed platelets with small size or one-dimensional worm-like micelles are assembled if the liquid crystalline order of the corona segments is lost. It is speculated that the preferred parallel arrangement of liquid crystalline block enables it to expose more growth front of crystals. Accordingly, epitaxial crystallization will proceed readily, leading to fabrication of the well-defined single crystals. © 2016 American Chemical Society.

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.

A simple electrochemical biosensor was developed based on an N-doped carbon quantum dot (NCQD) modified glass carbon electrode (NCQD/GCE). The modified electrode displayed a good linear and broad response for the detection of dopamine (DA). The as-prepared biosensor also exhibited satisfactory selectivity even with interference of ascorbic acid (AA) and uric acid (UA). Inorganic ions also had no effect on detecting DA. © The Royal Society of Chemistry 2015.

The glucose-responsive amphiphilic poly(PEGMA-co-AAPBA) copolymer micelles as drug carriers have been developed using 3-phenylpyruvic acid (3-PPA) as photoinitiator. Under the light irradiation, 3-PPA could be self-polymerized into the trimer structure to execute the emulsifier and initiator functions that confirmed by gas chromatography-mass spectrum (GC-MS) analysis. The structure and morphology of resultant poly(PEGMA-co-AAPBA) micelles were characterized by 1H NMR and TEM. Insulin, as the model drug of diabetes, was loaded into micelles during the photopolymerization process. The as-prepared polymeric micelles exhibited the excellent glucose sensitivity. The loaded insulin could be released from micelles triggered by regulation of temperature and glucose concentration in the environment. The new drug carriers provided a potential application for the therapy of diabetes based on glucose-sensitive controlled drug delivery systems. © 2015, Springer-Verlag Berlin Heidelberg.

Glucose-sensitive and fluorescence copolymer micelles were designed and prepared via a combination of photoinitiated polymerization and enzymatic transesterification. The water-soluble photoinitiator and emulsifier 2-oxooctanoic acid self-polymerized dimer molecules under UV irradiation were characterized by mass spectrometry. The fluorescence dye (9-anthracene alcohol) and biocompatible hydrophilic chains [poly(ethylene glycol)] were introduced to the polymer chains during the photopolymerization and enzymatic transesterification processes. The as-prepared copolymers were confirmed by 1H-NMR spectroscopy, Fourier transform infrared spectroscopy, transmission electron microscopy, and dynamic light scattering. The resulting copolymers exhibited excellent glucose sensitivity and stability against protein. The optical fluorescence properties of the copolymer micelles were investigated with fluorescence spectrophotometry, fluorescence microscopy, and confocal laser scanning microscopy. Because of the amphiphilic feature, the micelles could be self-assembled and used to load insulin. The controlled release of insulin was evaluated and was triggered by glucose in vitro. This study provided a new strategy for fabricating functional carriers as self-regulated insulin-release systems. © 2015 Wiley Periodicals, Inc.
