Abstract:Electrospun technique has become the pivotal tool, which is a combination of multi-component compositions and fabrication techniques. The chemical, physical and biological properties of electrospun scaffolds can be adjusted by the fabrication techniques to match the different environment that the scaffolds applied in. Functional nanofibrous scaffolds produced by electrospinning have great potential in many biomedical applications, such as tissue engineering, wound dressing, enzyme immobilization and drug (gene) delivery. The property of the nanofibrous scaffold can be further improved with innovative development in electrospinning processes, such as coaxial electrospinning and two-component electrospinning. Post modifications of electrospun membranes also provide effective means to render the electrospun scaffolds with controlled anisotropy and porosity. In this article, we will review the techniques and post modification methods of functional electrospun nanofibrous scaffolds applied in biomedical fields.
Key words: electrospinning techniques; nanofibrous; modification; biomedical applications
