Biodegradable nanofibers are expected to be promising scaffold materials for biomedical engineering, however, biomedical applications require control of the degradation behavior and tissue response of nanofiber scaffolds in vivo. For this purpose, electrospun nanofibers of poly(hydroxyalkanoate)s (PHAs) and poly(lactide)s (PLAs) were subjected to degradation tests in vitro and in vivo. In this ...

Inactivated Hemagglutinating Virus of Japan Envelope (HVJ-E) was immobilized on electrospun nanofibers of poly(ε-caprolactone) by layer-by-layer (LbL) assembly technique. The precursor LbL film was first constructed with poly-L-lysine and alginic acid via electrostatic interaction. Then the HVJ-E particles were immobilized on the cationic PLL outermost surface. The HVJ-E adsorption was confirme...

Tin oxide (SnO2) nanofibers are successfully prepared by electrospinning homogeneous viscous solutions of tin acetate in polyvinylpyrrolidone (PVP). The electrospinning is carried out by applying a DC voltage to the tip of a syringe and maintaining the tip to collector distance (TCD), i.e. at DC electric field of 1.25 kV∙cm−1. The electrospun nanofibers are calcined between 550 ̊C and 650 ̊C for ...

Polyamide 6 (PA6) was melt-blended with an intumescent flame retardant (FR), multi-wall carbon nanotubes (MWNTs), and nanoclay particles to produce multi-component FR-PA6 nanocomposites. FR-PA6 nanofibers were processed from varied nanocomposite formulations via electrospinning. Electrospinnability, morphology, along with combustion and thermal properties of the nanofibers were investigated. Bo...

Axonal re-myelination in injured central nervous system (CNS) has been a scientific challenge. Focal delivery of Oligodendrocyte Progenitor Cells (OPCs) provides promising approach. We used a novel bioengineering technique to create co-electrospun nanofibers of Gelatin and Poly-ɛ-caprolactone (PCL) to be used as a scaffold for neural tissue regeneration. Growth and differentiation of Oligodendr...

Poly(ε-caprolactone) (PCL) nanofibers were prepared by electrospun, on which the cis-diamminediiodoplatinum (cis-DIDP) was loaded, cis-DIDP@PCL, which effectively overcame cis-DIDP from dissociation or premature interaction with other bimolecular groups. Meanwhile, the toxicity and cross-resistance of cis-DIDP were reduced greatly. In vitro, cis-DIDP released from the PCL nanofibers eradicated ...

Cancer has become the leading cause of death worldwide; early diagnosis and treatment of cancers is critical for the survival of the patients. The concentration of cancer markers in easy-to-access biological fluids can provide great assistance in screening for occult primary cancers, distinguishing malignant from benign findings, determining prognosis and prediction for cancer patients. The mul...

Periodontitis is a widespread dental disease affecting 10 to 15% of worldwide adult population, yet the current treatments are far from satisfactory. The human periodontal ligament stem cell is a promising potential seed cell population type in cell-based therapy and tissue regeneration, which require appropriate scaffold to provide a mimic extracellular matrix. Zein, a native protein derived f...

In this study, a mixture of poly(vinyl alcohol) (PVA) and chitosan oligosaccharides (COS) was electrospun with silver nanoparticles (AgNPs) to produce fibrous mats for use in wound healing. The AgNPs were reduced by COS prior to electrospinning or Ag(+) was reduced via ultraviolet irradiation in nanofibers. The morphologies of the PVA/COS/AgNO3 and PVA/COS-AgNP nanofibers were analyzed by scann...

Cold-plate electrospun silk nanofibers look to be a promising scaffold for tissue engineering due to their ability to be controlled in the 3D nanofibrous form. They can be manipulated to resemble the dermis and other structures compatible with tissue repair.
