A two-enzyme immobilization approach using carbon nanotubes/silica as support.
Biotechnol. Prog. 31(1) , 42-7, (2015) Multiple enzyme mixtures are attractive for the production of many compounds at an industrial level. We report a practical and novel approach for coimmobilization of two enzymes. The system consists of a silica microsphere core coated with two layers of indiv... |

Xerogel-sequestered silanated organochalcogenide catalysts for bromination with hydrogen peroxide and sodium bromide.
Molecules 20 , 9616-39, (2015) While H2O2 is a powerful oxidant, decomposing into environmentally benign H2O and O2, a catalyst is often required for reactions with H2O2 to proceed at synthetically useful rates. Organotellurium and organoselenium compounds catalyze the oxidation of halide ... |

PAH/DAS covalently cross-linked layer-by-layer multilayers: a "nano-net" superstratum immobilizes nanoparticles and remains permeable to small molecules.
Soft Matter 11 , 6859-65, (2015) A "nano-net" superstratum strategy is developed to stabilize layer-by-layer (LbL) films that incorporate nanoparticles. The superstratum immobilizes silica, gold, or magnetic nanoparticles and at the same time is permeable to small molecules. Unlike most stra... |

Fabrication of fibrous amidoxime-functionalized mesoporous silica microsphere and its selectively adsorption property for Pb(2+) in aqueous solution.
J. Hazard. Mater. 297 , 66-73, (2015) Fibrous cyano-modified mesoporous SiO2 microspheres with specific surface area of ca. 300 m(2) g(-1) have been successfully fabricated respectively by in-situ synthesis and post-modification methods, based on the hydrolysis of ethyl silicate in the presence o... |

Effect of surface functionality of silica nanoparticles on cellular uptake and cytotoxicity.
Mol. Pharm. 11(10) , 3642-55, (2014) Mesoporous silica nanoparticles (MCM-41) with different surface chemistry were used as carrier system to study its influence on drug delivery and anticancer activity of curcumin (CUR). CUR was encapsulated in pristine MCM-41 (hydrophilic and negatively charge... |

Large-scale high-quality 2D silica crystals: dip-drawing formation and decoration with gold nanorods and nanospheres for SERS analysis.
Nanotechnology 25(40) , 405602, (2014) High-quality colloidal crystals (CCs) are important for use in photonic research and as templates for large-scale plasmonic SERS substrates. We investigated how variations in temperature, colloid concentration, and dip-drawing parameters (rate, incubation tim... |

Mesoporous silica coated gold nanorods loaded doxorubicin for combined chemo-photothermal therapy.
Int. J. Pharm. 470(1-2) , 1-7, (2014) The efficacy of the combined chemo-photothermal therapy, using a mesoporous silica-coated gold nanorods loaded DOX (pGNRs@mSiO2-DOX), was consistently tested both in vitro and in vivo. The prepared nanoparticles that were characterized using transmission elec... |
