Abstract In this study, a poly l -lactic acid (PLLA) fibrous mat was prepared by electrospinning, followed by surface modification with polydopamine (PDA), based on its strong adhesion performance and self-polymerization of dopamine. The PDA coating on the fibrous mat surface provided a reaction platform for heparin via a Michael-type addition reaction and a reductive surface for Ag+ in situ formation of silver nanoparticles (AgNPs) in AgNO3 solution. The structure and chemical composition of th...

Electrospinning has been widely recognized as a facile and scalable method for fabricating fibrous materials, which could be used as adsorption materials because of their high surface area. Surface molecular imprinting based on adsorption materials has shown excellent adsorption performance, including large binding capacity, a fast adsorption rate and selective adsorption. In this study, electrospinning and surface molecular imprinting were used together to prepare a surface molecularly imprinte...

AbstractElectrospinning has been used to fabricate random and aligned poly (L-lactic acid) (PLLA) fibers with three kinds of diameter under optimal conditions. The main purpose of this paper was to investigate the influence of the diameter and orientation of fibers on the bioactivity of endothelial cells, especially on the inflammatory cytokines expression. The morphology of electrospun fibers and the cells on the fibers after 3 and 6 days culture were observed by scanning electron microscopy. A...

Electrospun poly(l-lactic acid) (PLLA) nanofiber mats were successfully modified by deposition of multilayers with chitosan (CS), heparin (Hep) and graphene oxide (GO) through electrostatic layer-by-layer (LBL) self-assembly method. In this study, the surface properties of PLLA nanofiber mats before and after modification were investigated via scanning electron microscope (SEM), atomic force microscopy (AFM), attenuated total reflectance fourier transformation infrared spectroscopy (ATR-FTIR), X...

Abstract In this study, different nanoporous polyethersulfone (PES) fiber mats were fabricated for bilirubin adsorption via electrospinning technique with different solvent compositions of tetrahydrofuran (THF) and N,N-dimethylformamide (DMF). The porous structure of the PES fiber mats was investigated via scanning electron microscope (SEM) and Brunauer-Emmett-Teller (BET) measurements. The results showed that the PES fiber mats electrospun prepared with THF/DMF (1/3) exhibited the largest surfa...

Abstract A simple but straightforward approach was reported to prepare fiber mats modified with fibronectin (Fn) protein for endothelial cells activity study. Based on the self-polymerization and strong adhesion feature of dopamine, poly L-Lactic acid (PLLA) fibers mat was modified via simply immersing them into dopamine solution for 16 h. Subsequently, Fn was immobilized onto the fiber mats surface by the coupling reactive polydopamine (PDA) layer and Fn. Attenuated total reflectance Fourier tr...
