Poly-L-lactic acid (PLLA) electrospun nanofiber scaffold is one of the most commonly used synthetic polymer scaffolds for bone tissue engineering application. However, PLLA is hydrophobic in nature, hence does not maintain proper cell adhesion and tissue formation, moreover, it cannot provide the osteo-inductive environment due to inappropriate surface characteristic and the lack of surface mot...

Morphological characteristics of electrospun PVA nanofibers were investigated in terms of polymer molecular weight was reported in this paper. The change in the morphology depending on the polymer concentration of electrospinning solution and the applied voltage were addressed. The fiber diameter increased with the increase in the molecular weight and polymer concentration and applied voltage a...

Aluminum nitride (AlN) hollow nanofibers were synthesized via plasma-enhanced atomic layer deposition using sacrificial electrospun polymeric nanofiber templates having different average fiber diameters (~70, ~330, and ~740 nm). Depositions were carried out at 200°C using trimethylaluminum and ammonia precursors. AlN-coated nanofibers were calcined subsequently at 500°C for 2 h to remove the sa...

In this study, Silk Fibroin (SF)/Polycaprolactone (PCL) composite nanofiber mats were fabricated using an electrostatic spinning technology employing different drum rotation speeds. The morphology and tensile performance of the resulting nanofiber mats were characterized using thermal field emission scanning electron microscopy, multi-layer image fusion technology, pore size distribution analys...

Electrospinning method was used to fabricate poly(L-lactide-co-D,L-lactide) (PLDLA) nanofiber non-woven membranes. The structure and morphology of the electrospun membranes were investigated by a scanning electron microscope (JEOL) after a gold coating. The diameter of the electrospun fiber was measured by Adobe Photoshop 5.0 software from the SEM pictures. SEM images showed that the fiber diam...

IMPORTANCE Cell seeding throughout the thickness of a nanofiber construct allows for patient-specific implant alternatives with long-lasting effects, earlier integration, and reduced inflammation when compared with traditional implants. Cell seeding may improve implant integration with host tissue; however, the effect of cell seeding on thick nanofiber constructs has not been studied. OBJECTI...

Solution blow spinning (SBS) is an innovative process for spinning micro/nanofibers. In this paper, polyamic acid (PAA) nanofibers were fabricated via a SBS apparatus and then imidized into polyimide (PI) nanofibers via thermal process. The morphology and diameter distributions of PAA nanofibers were determined by scanning electron microscope (SEM) and Image Tool software, the processing parame...
