A novel nanofibrous film chemosensor was fabricated by copolymerization and electrospinning, which exhibited signaling behaviors for Zn. Upon addition of Zn, the sensor film exhibited obvious fluorescence enhancement in a linear fashion. Owing to a larger surface area and high permeability, the selectivity and sensitivity of the nanofibrous film for Zn were satisfactory and achieving a limit of...

In this study, the influence of the morphology on the electrocatalytic activity of nickel oxide nanostructures toward methanol oxidation is investigated. Two nanostructures were utilized: nanoparticles and nanofibers. NiO nanofibers have been synthesized by using the electrospinning technique. Briefly, electrospun nanofiber mats composed of polyvinylpyrolidine and nickel acetate were calcined a...

A novel surface modification strategy for an electrospun nanofibrous film was reported, allowing detection and removal of copper ions in the aqueous solution. This reusable dual fluorescent-colorimetric nanofibrous film can be utilized conveniently to achieve real-time naked-eye sensing in aqueous medium just like using a test paper.

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

Regeneration of fractured or diseased bones is the challenge faced by current technologies in tissue engineering. The major solid components of human bone consist of collagen and hydroxyapatite. Collagen (Col) and hydroxyapatite (HA) have potential in mimicking natural extracellular matrix and replacing diseased skeletal bones. More attention has been focused on HA because of its crystallograph...

Protein-coated resorbable synthetic polymeric nanofibrous membranes are promising for the fabrication of advanced skin substitutes. We fabricated electrospun polylactic acid and poly(lactide-co-glycolic acid) nanofibrous membranes and coated them with fibrin or collagen I. Fibronectin was attached to a fibrin or collagen nanocoating, in order further to enhance the cell adhesion and spreading. ...

The need exists for biomaterials that prevent biofilm formation and associated infections. In this report, we have studied the synthesis, processing, and antimicrobial behavior of new silver-containing thermoplastic hydrogel nanofibrous webs. Thermoplastic hydrogels were synthesized from multiblock PEG-POSS polyurethanes (PEG: poly(ethylene gylcol); POSS: polyhedral oligosilsesquioxane) and ele...

Skin drug delivery systems with controlled release are suitable means for the local transfer of pharmaceutical compounds to the damaged and healthy layers of skin. Nanofibrous membrane prepares uniform moisture in the wound environment with less accumulation of fluid secretion due to its variable pore size. Electrospinning takes advantage of using herbal extracts in the form of electrospun nano...
