Abstract Details: The global market for bone graft substitutes will worth US$ 3.2 billion in 2022. The market for hip and knee orthopaedic surgical joint replacement products is expected to reach US $33 billion in the same year. Hence, the development of materials and strategies that can promote faster healing of prosthetic devices and improved regeneration of bony defects is of high interest. Graphene and its derivatives (graphene oxide and reduced graphene oxide) have remarkable mechanical properties, can be chemically modified and allow the attachment of molecules and proteins. Due to these characteristics, these carbon-based materials have received increasing attention for several biomedical applications. As graphenes can improve mechanical properties of several biomaterials, induce, and increase cell differentiation towards osteoblasts, they have emerged as alternatives to promote bone regeneration. In this seminar, Dr. Rosa will discuss the key achievements made with graphenes for bone tissue engineering and the possible graphene-mediated mechanisms leading to the enhanced regeneration.

About The Speaker: Dr. Vinicius ROSA Assistant Professor, Oral Sciences, Faculty of Dentistry, NUS. Faculty, Centre for Advanced 2D Materials and Graphene Research Centre, NUS. Dr. Rosa obtained D.D.S. (Doctor of Dental Surgery) in 2005 and has received the "Academy of Dental Materials Student Award", an award presented by the Academy of Dental Materials to the most outstanding student researcher in the field of Dental Materials. In 2007, the M.Sc. dissertation on the deterioration of strength of bioceramics received the George C. Paffenbarger Research Award that recognizes the best paper in the field of Dental Materials annually. In 2010, Dr. Rosa defended the Ph.D. thesis “Dental Pulp Tissue Engineering in Full-length Human Root Canals” and started studying the interactions of material with cells and host living tissue. The article arising from it thesis is in the top 1% globally for Dentistry and has received the Edward H. Hatton Award. In 2012, Dr. Rosa joined Faculty of Dentistry/NUS to develop with novel cell models and materials for tissue regeneration. In 2014, Dr. Rosa was appointed as a Faculty by the Centre for Advanced 2D Materials and Graphene Research Centre /NUS where focus on the use of graphene to improve bone tissue tissue engineering and regeneration.
