Photoluminescent fullerene nanoparticles/nanofibers have potential applications in bioimaging. A novel fluorescent nanofibrous material, consisting of fullerene nanoparticles and poly(L-lactide) (PLLA), was fabricated via a simple electrospinning method, and the composite nanofibers were characterized by various techniques such as scanning electron(More)
Novel biocompatible poly(lactide-co-glycolide) (PLGA) nanofiber mats with favorable biocompatibility and good mechanical strength were prepared, which could serve as an innovative type of tissue engineering scaffold or an ideal controllable drug delivery system. Both hydrophobic and hydrophilic drugs, Cefradine and 5-fluorouracil were successfully loaded(More)
The surface modification of hydroxyapatite (HA) nanoparticles by the ring opening polymerization (ROP) of gamma-benzyl-L-glutamate N-carboxyanhydride (BLG-NCA) was proposed to prepare the poly(gamma-benzyl-L-glutamate) (PBLG)-grafted HA nanoparticles (PBLG-g-HA) for the first time. HA nanoparticles were firstly treated by 3-aminopropylthriethoxysilane (APS)(More)
In order to realize controlled dual release of two hydrophobic drugs with distinct rates in a vehicle, novel poly(lactic-co-glycolic acid) (PLGA) composite nanofibers encapsulated with micelles were successfully fabricated by "emulsion-electrospinning." Brefeldin A (BFA) was firstly embedded in monomethoxy-poly(ethylene glycol)-b-poly(L-lactide)(More)
In this article, a nonenzymatic sensor based on Ni(OH)2/electroreduced graphene oxide (ERGO)-multiwalled carbon nanotube (MWNT) nanocomposites is fabricated via convenient electrodeposition of Ni(OH)2 nanoparticles on ERGO-MWNT film modified glass carbon electrode (GCE). Graphene oxide (GO) sheets can serve as surfactants to stabilize the dispersion of(More)
Postoperative adhesion (POA) is a serious event that always causes chronic pain and functional obstruction. Up to now, a variety of matrices prepared by diverse technologies have been employed as the physical barriers to prevent POA. Among them, the electrospun fibers of biodegradable polymers exhibit more obvious advantages, such as large surface area,(More)
Polymer membranes have been widely used in guided tissue regeneration (GTR) and guided bone regeneration (GBR). In this review, various commercially available membranes are described. Much attention is paid to the recent development of biodegradable polymers applied in GTR and GBR, and the important issues of biodegradable polymeric membranes, including(More)
A smart ZnO@PNIPAM hybrid was prepared by grafting thermal responsive poly(N-isopropylacrylamide) (PNIPAM) on zinc oxide (ZnO) nanoparticles via surface-initiated atom transfer radical polymerization (ATRP). The thermal gravimetric analysis (TGA) shows that the grafting amount of PNIPAM was about 38%, and the SEM images show that the PNIPAM chains can(More)
The paper describes a study on the fluorescence of a Eu-doped Mg-Al layered double hydroxide (Eu-doped LDH) response to glutamic acid (Glu). Various characterizations (UV-Vis transmittance, TG-DTA and IR-spectrum) indicated that there is an interaction between the Eu-doped LDH and Glu. Fluorescent study was found that the red emissions resulted from(More)
Migraine may affect the autonomic nervous system, but the mechanisms remain unclear. The sympathetic and parasympathetic nervous systems may play different roles in the attack. To explore the effect of blocking the cervical sympathetic nerve on vasodilation of the meningeal vessels, jugular vein calcitonin gene-related peptide (CGRP) and meningeal blood(More)
