Departmental Seminar

Blueprint of a biomineral – Iron teeth, X-ray µCT and AI

Professor Jeremy Shaw
University of Western Australia

Dr Shaw is the platform leader for X-ray micro-CT at UWA’s Centre for Microscopy, Characterisation and Analysis (CMCA). He has been awarded a Stjepan Marcelja Visiting Fellowship to work with ANU’s Dr Philipp Loesel, with a view to learn and deploy Biomedisa as a tool for researchers in WA. Dr Shaw’s presentation will briefly cover µCT at UWA and some of the projects that hope to benefit from the functionality provided by Biomedisa. Dr Shaw will then focus on an interesting problem in the field of biomineralization that has perhaps been waiting for an AI-based solution. Biominerals, such as teeth, bone and shell are formed by complex cellular mechanisms that dictate the precipitation of specific mineral phases into specialised morphologies. One of the most intriguing biomineralized structures are the teeth formed by a group of marine molluscs called chitons. These animals build an organic scaffold upon which a range of minerals form, including the iron oxide magnetite. The scaffold facilitates mineral growth at the nano- to micron-scale within the confines of a tooth only 300 microns in size. Using a combination of X-ray and electron imaging, can AI be used to characterise the complete organic structure of a chiton tooth?
