Electrospinning: Technologies and Applications in the Biomedical Field, with Min Wang PhD CSci CEng, Department of Mechanical Engineering, The University of Hong Kong

Abstract
Electrospinning is not new. But it has attracted great attention in the biomedical field since two decades ago thanks to the distinctive properties of electrospun nanofibrous structures. Therefore, publications on electrospinning and electrospun structures have been on the exponential increase over the past 20 years, testifying the worldwide interest in this technology or this group of technologies. Electrospun nanofibers can have diverse applications such as filtration, sensors, cosmetics, etc. The intense interest of using electrospun fibrous structures in medicine stems primarily from their nanofibrous morphologies, which resemble the nanofibrous extracellular matrix of human body tissues. Also, electrospun nanofibers can serve as excellent delivery vehicles of bioactive agents (drugs, biomolecules, genes, etc.) in the body. The principle of electrospinning is simple; and parameters for the basic electrospinning technique are not many. However, with innovative modifications of the basic electrospinning technique, introduction of new fiber collecting techniques, and developments of techniques such as coaxial electrospinning and emulsion electrospinning, possibilities for creating fibrous structures with distinctive and desirable properties appear to be boundless. For over 10 years now, we have been conducting investigations into electrospinning technologies and electrospun nanofibrous structures for biomedical applications. For the controlled release of biomolecules such as growth factors, emulsion electrospinning is often employed to form nanofibrous delivery systems. For the controlled, simultaneous or sequential release of two or more growth factors for tissue regeneration, we have developed new electrospinning technologies and fabricated bi- or tricomponent fibrous delivery vehicles. Biological assessments have affirmed synergistic effects of dual delivery and controlled release of growth factors from novel tissue engineering scaffolds. Multicomponent and multifunctional scaffolds have also been made and studied for regenerating complex human body tissues such as gastrointestinal tract. We have also demonstrated that electrospinning and nanotechnology can be used together to form combination devices for combating complex medical problems.
