Tissue engineering is a technique by which a live tissue can be re-constructed and one of its main goals is to associate cells with biomaterials. Electrospinning is a technique that facilitates the production of nanofibers and is commonly used to develop fibrous scaffolds to be used in tissue engineering. In the present study, a different approach for cell incorporation into fibrous scaffolds w...

Biodegradable poly(L-lactide acid) (PLLA) nanofiber membranes were prepared by electrospinning of PLLA and poly(ethylene oxide) (PEO). The selective removal of PEO by water allows to obtain smaller fiber diameters and to increase the porosity of the membranes in comparison to PLLA membranes obtained under the same electrospinning conditions. After removal of PEO membranes with fiber sizes of 26...

Uniform deposition of nanofibers in the massive electrospinning process is critical in the industrial applications of nanofibers. Tip-Induced Electrospinning (TIE) is a cost-effective large-scale nanofiber-manufacturing method, but it has poor deposition uniformity. An auxiliary conductive electrode connected to the emitting electrode was introduced to improve the deposition uniformity of the n...

We present a method for the electrospinning of conducting polymeric composite nanofibers using a poly(dimethyl siloxane) (PDMS)-based microfluidic device. To scale-up the process and spin multicomponent systems, we designed a unique multi-spinnerette electrospinning device using microchannels cast in PDMS. Nanofibers of poly (vinylpyrrolidone) and its composite with polypyrrole were successfull...

Objective(s):The aim of this study was to prepare electrospun nanofibers of celecoxib using combination of time-dependent polymers with pectin to achieve a colon-specific drug delivery system for celecoxib. Materials and Methods:Formulations were produced based on two multilevel 22 full factorial designs. The independent variables were the ratio of drug:time-dependent polymer (X1) and the amoun...

in this work, cofe2o4 nanoparticles have been prepared by co-precipitation technique. the synthesized cofe2o4 nanoparticles were applied in the preparation of cofe2o4/polyacrylonitrile fiber nanocomposites by the electrospinning process. the prepared nanoparticles and nanofibers were characterized using the scanning electron microscopy (sem) and x-ray diffraction methods. the results manifested...
