Electrospinning of bioinspired polymer scaffolds

Abstract

Electrospinning is a technique used in the production of polymer nanofibre meshes. The use of biodegradable and biocompatible polymers to produce nanofibres that closely mimic the extracellular matrix (ECM) of different tissues has opened a wide range of possibilities for the application of electrospinning in Tissue Engineering. It is believed that nanofeatures (such as voids and surface cues) present in nanofibre mesh scaffolds, combined with the chemical composition of the fibres, can stimulate cell attachment, growth and differentiation. Despite the widespread use of electrospun nanofibres in tissue engineering, the present chapter will focus on the advances made in the utilisation of these materials in bone, cartilage and tooth related applications. Several aspects will be taken into consideration, namely the choice of polymers, the surface modification of the nanofibres in order to achieve mineralisation, and also the biological application of such materials.
