objective(s): to improve water stability of electrospun chitosan/ polyethylene oxide (peo) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  materials and methods: different amounts of genipin were added to the chitosan/peo solutions, chitosan/peo weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

Electrospun polycaprolacyone/polymethacrylic acid graft copolymer nanofibers (PCL/MAA) containing silver nanoparticles (AgNPs) were synthesized for effective wound disinfection. Surface morphology, AgNPs content, water uptake of electrospun PCL/MAA graft copolymer nanofibers without and with AgNPs, and levels of AgNPs leaching from the nanofibers in water as well as antimicrobial efficacy were ...

semelil is an herbal-based compound which is used for the treatment of chronic wounds, especially diabetic foot ulcers. on the other hand, electrospun nanofibers have many characteristics such as mimicking extracellular matrix structure, efficiency as bacterial barrier, appropriate water vapor transmission rate, and provision of adequate gaseous exchange which make them ideal candidates for wou...

Poly(L-lactide-co-ε-caprolactone) nanofibers with heparin incorporated were successfully fabricated by coaxial electrospinning. The morphologies of electrospun nanofibers were studied by scanning electron microscopy (SEM), and a significant decrease in fiber diameter was observed with increasing heparin concentration. The transmission electron microscopy (TEM) images indicated that coaxial elec...

Electrospinning has been recognized as an efficient technique for the fabrication of polymernanofibers. Recently, various polymers have successfully been electrospun into ultrafine fibers.Electrospinning is an extremely promising method for the preparation of tissue engineering scaffolds.In this study, nanofibers gelatin was electrospun at 20% v/v optimized content. To produce...

objective(s): electrospun nanofibrous mats of poly(lactic acid) (pla) and nanohydroxyapatite (nano-ha) were prepared and proliferation and differentiation of mesenchymal stem cells on the prepared nanofibers were investigated in this study. materials and methods: pla/nano-ha nanofibers were prepared by electrospinning. the effects of process parameters, such as nano-ha concentration, distance, ...

Objective(s): To improve water stability of electrospun chitosan/ Polyethylene oxide (PEO) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  Materials and Methods: Different amounts of genipin were added to the chitosan/PEO solutions, chitosan/PEO weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

The objective of this study was to compare the adsorption/desorption of target compounds on homemade electrospun nanofibers, polystyrene (PS) nanofibers, acrylic resin (AR) nanofibers and PS-AR composite nanofibers with Tenax TA. Ten volatile organic compounds (VOCs) were analyzed by preconcentration onto different sorbents followed by desorption (thermal and solvent orderly) and analysis by ca...

In this study, self-assembly regenerated silk fibroin (RSF) nanofibers were prepared and observed by Atomic Force Microscope (AFM). Then RSF films containing nanospheres and nanofibers were prepared and dissolved with poly (L-lactide-co-ε-caprolactone) (PLCL) with a blending ratio of 30/70 in hexafluoro-2-propanol (HFIP). In order to determine whether different nanostructures in the solution in...

Epoxy in electrospun nanofibers acting as adhesive generates junctions between nanofibers and thus forms stable three-dimensional networks.
