  • Synergistic toughening of bioinspired poly(vinyl alcohol)-clay- nanofibrillar cellulose artificial nacre
    ACS Nano, 2014
    Co-Authors: Jianfeng Wang, Ling Lin, Qunfeng Cheng, Lei Jiang
    Abstract:

    Inspired by the layered aragonite platelet/nanofibrillar chitin/protein ternary structure and integration of extraordinary strength and toughness of natural nacre, artificial nacre based on clay platelet/nanofibrillar cellulose/poly(vinyl alcohol) is constructed through an evaporation-induced Self-Assembly Technique. The synergistic toughening effect from clay platelets and nanofibrillar cellulose is successfully demonstrated. The artificial nacre achieves an excellent balance of strength and toughness and a fatigue-resistant property, superior to natural nacre and other conventional layered clay/polymer binary composites.

  • lysozyme collagen multilayers layer by layer deposited nanofibers with enhanced biocompatibility and antibacterial activity
    Materials Science and Engineering: C, 2020
    Co-Authors: Mengqin Yuan, Yanxiang Cheng, Wei Xiang, Dan Li, Hongbing Deng
    Abstract:

    Abstract Biological meshes have always posed a challenge in biological medicine, for which nanocomposites with enhanced biocompatibility and antibacterial activity may be beneficial. In this study, lysozyme (LY) and collagen (Col) were alternately deposited on silk fibroin (SF) and nylon 6 (N6) composite nanofibrous mats using a layer-by-layer (LBL) Self-Assembly Technique. The mechanical properties, biocompatibility, and antibacterial activity of the LBL structured mats were characterized systematically to investigate the impact of the LBL process on the biological properties of SF/N6 nanofibrous mats. Our results showed that the effective deposition of LY and Col may affect the surface topography, mechanical properties, and wetting behavior of the SF/N6 nanofibrous mats. Moreover, LBL structured mats exhibited excellent biocompatibility and antibacterial properties. Among all the tested mats, those coated with 10 bilayers of LY and Col displayed the best biocompatibility, and relatively good mechanical and antibacterial properties. Thus, LBL structured mats, especially those with a 10 bilayer coating, are potentially valuable in clinical therapy for pelvic organ prolapse in the future.

  • lbl structured chitosan layered silicate intercalated composites based fibrous mats for protein delivery
    Carbohydrate Polymers, 2012
    Co-Authors: Liangqun Zheng, Yuli Zhu, Rong Huang, Hongbing Deng
    Abstract:

    Organic rectorite (OREC) was used to prepare intercalated composites with chitosan. The negatively charged cellulose acetate (CA) fibrous mats were modified with multilayers of the positively charged chitosan or chitosan-OREC intercalated composites and the negatively charged bovine serum albumin (BSA) via electrostatic layer-by-layer (LBL) Self-Assembly Technique. The morphology and protein delivery properties of the resultant samples were investigated by regulating the number of deposition bilayers, the outermost layer and the composition of coating bilayers. The thickness of LBL films coated CA mats increased as the number of bilayers was increased and OREC was added. X-ray photoelectron spectroscopy indicated that chitosan and OREC were deposited on CA fibers. Small angle X-ray diffraction patterns showed that OREC was intercalated by chitosan. The in vitro BSA encapsulation and release experiments demonstrated that OREC could affect the degree of protein loading capacity and release efficiency of the LBL films coating.

  • layer by layer immobilization of lysozyme chitosan organic rectorite composites on electrospun nanofibrous mats for pork preservation
    Food Research International, 2012
    Co-Authors: Weijuan Huang, Hongbing Deng, Rong Huang, Yue Xue, Siyi Pan
    Abstract:

    Abstract Negatively charged electrospun cellulose acetate (CA) fibrous mats were modified with multilayers of the positively charged lysozyme (LY)–chitosan (CS)–organic rectorite (OREC) composites and the negatively charged sodium alginate (ALG) via layer-by-layer (LBL) Self-Assembly Technique. The morphology and antibacterial activity of the resultant samples were investigated by regulating the number of deposition bilayers, the composition of coating bilayers and the outermost layer. Field emission scanning electron microscopy images indicated that the average diameter of LY–CS–OREC/ALG film coating was larger than that of LY–CS/ALG film coating. X-ray photoelectron spectroscopy results implied that LY and OREC were successfully deposited on CA fibers. The LBL structured fibrous mats with the addition of OREC could enhance the degree of inhibition against Escherichia coli and Staphylococcus aureus . (LY–CS–OREC/ALG) 10.5 film coating with the best antibacterial activity, selected for preserving pork for 21 days, could extend the shelf-life of pork for about 3 days.

  • layer by layer structured polysaccharides film coated cellulose nanofibrous mats for cell culture
    Carbohydrate Polymers, 2010
    Co-Authors: Hongbing Deng, Xue Zhou, Xiaoying Wang, Chunyan Zhang, Bin Ding, Qiuhua Zhang
    Abstract:

    Abstract For the first time, a novel fibrous polysaccharide scaffold for cell culture was fabricated by the combination of electrospinning and electrostatic layer-by-layer (LBL) Self-Assembly Technique. Oppositely charged chitosan (CS) and alginate (ALG) in aqueous media were alternatively deposited onto the negatively charged cellulose nanofibrous mats which hydrolyzed from electrospun cellulose acetate mats. The morphology and biocompatibility of the resultant scaffolds were investigated by regulating the pH of dipping solutions, the number of deposition bilayers, and the composition of outermost layer. Field emission scanning electron microscopy images indicated that the scaffolds possessed the fibrous structure and the thickness of CS/ALG bilayer formed on fibers was estimated in the range of 8–15 nm. The X-ray photoelectron spectroscopy results verified the existence of nitrogen element of CS on the surface of LBL films. The cell culture experiments demonstrated that the scaffolds have good biocompatibility for Beas-2B human bronchial epithelial cells in vitro.
