Title: Engineering carbon nanomaterials and nanocomposites for biomedical applications
Dr. Wenhui Song has extensive expertise in science and engineering of biomaterials, polymers, nanomaterials and nanocomposites, as well as plastic/composite manufacturing technology from traditional extrusion, injection moulding, laminating to electrospinning and 3D printing etc. Her original work on the liquid crystalline phase of carbon nanotubes and mesophase of liquid crystalline polymers has contributed to the fundamental understanding of the self-organising behaviour of such nanoparticles and macromolecules. In parallel to basic research, she leads a research group working closely with industry on the development of real-world biomedical and engineering applications of nanomaterials and nanotechnology, such as controlled self-assembling nanostructured block-copolymer blends for pressure sensitive adhesives for personal care products, first implantable carbon nanotube fibre biosensors, high performance carbon nanotube-based field-emission devices, continuous flow processes of carbon nanomaterials and nanomedinces and first electrospining-coating implantable glucose biosensor. She has 50 publications in peer-reviewed journals including lead and corresponding author papers in the top quality journals, Science, Advanced Materials, Biomaterials etc. 1 patent pending, 4 book chapters, and 50 conference proceedings, and a number of invited lectures. Her original research has won 15 awards/prizes. She is a principal investigator/co-investigator in projects funded by EPSRC, TSB, DEFRA, Royal Society, LDA PARK Fund, UKIERI-DST and a number of industries. She is a member/panel member of the EPSRC College/TSB, member of Institute of Physics and Society of Chemical Industries, and a Fellow of the Nanotechnology Institute.
Owing to their low-dimensions at nanoscale, carbon base nanomaterials including carbon nanotubes, graphene and graphite nanosheets, show intriguing self-assembling behaviours. Their excellent anisotropic physical properties, large surface area, high electrochemical activity, low density and biochemical properties, are promising for more high-value-added products such as nanocomposites, electronics, energy storage and as well as biomedical application including sensors, devices and drug delivery. The innovations in controlled growth, post-synthesis functionalisation and process of carbon nanomaterials and their applications are still continuing. The talk presents the recent research progress on the processing carbon nanomaterials and their hybrid composites through various assembling and self-assembling strategies. The engineering and biomedical applications based on carbon nanotubes, graphene and their hybrid nanocomposites have been demonstrated from amperometric biosensors, to nerve repairs and cancer treatment.
