The debilitating effects of rotator cuff tears and the high incidence of failure associated with current grafts underscore the clinical demand for functional solutions for tendon repair and augmentation. To address this challenge, we have designed a poly(lactide-co-glycolide) (PLGA) nanofiber-based scaffold for rotator cuff tendon tissue engineering. In addition to scaffold design and character...

• Cubic Cu2O (20-−100 nm) synthesis on TiO2 nanofiber. Cube-on-nanofiber showed excellent photocatalytic H2 production and sulfamethoxazole decomposition. Surface modified confirmed by the energy-resolved distribution of electron traps (ERDT). Heterojunction interfaces between cube-on-nanofiber promote charge transfer provide active sites. We report a simple strategy for providing homogenous Ti...

Stabilizer-free polyaniline nanofiber aqueous colloids were obtained by the direct dispersing of polyaniline nanofiber prepared in the presence of β-cyclodextrin. The polyaniline nanofiber, the diameters of which are between 80 and 100 nm, can be steadily dispersed in near neuter (pH=6.5) aqueous solution for about 60 days without any steric or electrostatic stabilizer. © 2007 Elsevier B.V.

A highly crystalline polyethylene nanofiber is deflected by a cantilever under an atomic force microscope. The resulting approach and retract curves on both nanofiber and silicon substrate yield the Young's modulus of the nanofiber. The experiments show that the average Young's modulus of polyethylene nanofibers with diameters from 70 nm to 260 nm can be as high as 312 GPa.

Ba5Nb4O15 nanofibers with tailored nanofiber diameters are prepared via electrospinning, and treated in ammonia gas to synthesize niobate oxynitride nanofibers. Most importantly, the retain their fiber morphology during ammonolysis, diameter of converted fibers can be adjusted. Only a thorough characterization, including detailed Rietveld refinements, reveal that ammonolysis results not only Ba...

A composite nanofiber composed of three polymers, namely polyvinyl alcohol/polyvinyl pyrrolidone/polyethylene oxide, is produced. The experiments are constructed using design experiment techniques, Taguchi L9, L27, and Screening method. verified the analysis variance (ANOVA) method later a mathematical model developed regression impact electrospun processing parameters, applied voltage, flow ra...

Background: The aim of this study was to fabricate the poly caprolactone (PCL) aligned nanofiber scaffold and to evaluate the survival, adhesion, proliferation, and differentiation of rat hair follicle stem cells (HFSC) in the graft material using electrospun PCL nanofiber scaffold for tissue engineering applications. Methods: The bulge region of rat whisker was isolated and cultured in DMEM: n...

In this paper, a new image analysis based method for electrospun nanofiber diameter measurement has been presented. The method was tested by a simulated image with known characteristics and a real web. Mean (M) and standard deviation (STD) of fiber diameter obtained using this method for the simulated image were 15.02 and 4.80 pixels respectively, compared to the true values of 15.35 and 4.47 p...

DiameterJ is an open source image analysis plugin for ImageJ. DiameterJ produces ten files for every image that it analyzes. These files include the images that were analyzed, the data to create histograms of fiber radius, pore size, fiber orientation, and summary statistics, as well as images to check the output of DiameterJ. DiameterJ was validated with 130 in silico-derived, digital, synthet...
