Electrospun gelatin nanofibers attract great interest as a natural biomaterial for cartilage and tendon repair despite their high solubility in aqueous solution, which makes them also difficult to crosslink by means of chemical agents. In this work, we explore the efficiency of non-equilibrium atmospheric pressure plasma in stabilizing gelatin nanofibers. We demonstrate that plasma represents a...

Surface modified electrospun polyester (PET) nanofibers with cyclodextrin polymer (CDP) were produced (PET/CDP). CDP formation onto electrospun PET nanofibers was achieved by polymerization between citric acid (CTR, crosslinking agent) and cyclodextrin (CD). Three different types of native CD (α-CD, β-CD and γ-CD) were used to form CDP. Water-insoluble crosslinked CDP coating was permanently ad...

Electrospinning is a versatile technique that has gained popularity for various biomedical applications in recent years. Electrospinning is being used for fabricating nanofibers for various biomedical and dental applications such as tooth regeneration, wound healing and prevention of dental caries. Electrospun materials have the benefits of unique properties for instance, high surface area to v...

The accumulation of heavy metals in the human body and/or in the environment can be highly deleterious for mankind, and currently, considerable efforts have been made to develop reliable and sensitive techniques for their detection. Among the detection methods, chemical sensors appear as a promising technology, with emphasis on systems employing optically active nanofibers. Such nanofibers can ...

conventional transdermal drug delivery systems (tdds) have been designed for drug delivery through the skin. these systems use the permeability property of stratum corneum, the outermost surface layer of the skin. applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofiber...

scaffold design has pivotal role in tissue engineering. in the present study, we modified the surface of electrospun poly(caprolactone) (pcl) nanofibers to improve their compatibility with living medium and to show the potential application of pcl nanofibers as a artificial extracellular matrix using in tissue-engineering. pcl nanofibers were fabricated by electrospinning method. to graft gelat...

A microfluidic device is fabricated to characterize the streaming electrokinetic potential on the surface of charged electrospun nanofibers. The electrodes are made of evaporating with Ti and Au on an insulator, Pyrex® wafer, and are covered by a PDMS microchannel to form a microfluidic channel. The cationic or anionic charges of the electrospun charged nanofibers on the electrodes are interact...

The AgNPs has spheric...

The current of uni-axially aligned electrospun ZnO nanofibers is modulated reversibly under UV irradiation, with the sensitivity of the UV nanosensors depending on the surface coating of the nanofibers, due to the effect on the photo-generated current.

Electrospun membranes were studied for the chemical deactivation of threat agents by means of enzymatic proteins. Protein loading and the surface chemistry of hybrid nanofibers influenced the efficacy by which embedded enzymes could digest the substrate of interest. Bovine serum albumin (BSA), selected as a model protein, was electrospun into biologically active fibers of poly(vinyl alcohol), P...
