Chitin is a representative biomass resource comparable to cellulose. Although considerable efforts have been devoted to extend novel applications to chitin, lack of solubility in water and common organic solvents causes difficulties in improving its processability and functionality. Ionic liquids have paid much attention as solvents for polysaccharides. However, little has been reported regardi...

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...

Nanofiber mats have been widely applied in various biomedical fields such as drug delivery, tissue repair and wound dressing. In this study, the curcumin-loaded mesoporous silica incorporated nanofiber mats were prepared using blend electrospinning of curcumin-loaded mesoporous silica nanoparticles (CCM-MSNs) and polyvinyl pyrrolidone (PVP) for hemostasis. The prepared mats were then evaluated ...

This paper focuses on application of co-axial electrospinning technique to the development of nanofiber reinforced transparent composites. Investigations have been done on fabrication and functionalization of the transparent composites with improved mechanical properties, thermal properties and shielding ability for ultraviolet radiations. In the fabrication, PMMA, a polymer with excellent visi...

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...

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.
