Fabrication of Nanohydroxyapatite/Poly(caprolactone) Composite Microfibers Using Electrospinning Technique for Tissue Engineering Applications

Electrospinning Natural Polymers for Tissue Engineering Applications

Electrospinning is an efficient method by which to produce scaffolds composed of nanoscale to microscale fibers, which are comparable to the fiber diameters of native components of the extracellular matrix. In electrospinning, a polymer solution is pumped through a syringe that is connected to a high voltage source. As a droplet forms at the tip of the needle, electrostatic repulsions form long...

Fabrication of Porous Hydroxyapatite-Gelatin Composite Scaffolds for Bone Tissue Engineering

Background: engineering new bone tissue with cells and a synthetic extracellular matrix represents a new approach for the regeneration of mineralized tissues compared with the transplantation of bone (autografts or allografts). Methods: in this study, to mimic the mineral and organic component of natural bone, hydroxapatite (HA) and gelatin (GEL) composite scaffolds were prepared. The raw mater...

Fabrication of Chitosan Based Nanofibrous Scaffold Using Free Surface Electrospinning for Tissue Engineering Application

Electrospinning of polymeric nanofibers for tissue engineering applications: a review.

Interest in electrospinning has recently escalated due to the ability to produce materials with nanoscale properties. Electrospun fibers have been investigated as promising tissue engineering scaffolds since they mimic the nanoscale properties of native extracellular matrix. In this review, we examine electrospinning by providing a brief description of the theory behind the process, examining t...

Electrospinning polyaniline-contained gelatin nanofibers for tissue engineering applications.

Polyaniline (PANi), a conductive polymer, was blended with a natural protein, gelatin, and co-electrospun into nanofibers to investigate the potential application of such a blend as conductive scaffold for tissue engineering purposes. Electrospun PANi-contained gelatin fibers were characterized using scanning electron microscopy (SEM), electrical conductivity measurement, mechanical tensile tes...
