Calcium phosphates bone cements are widely used for bone-replacement materials due to their chemical similarity to natural bone but also their ability to set and harden in situ and their ability to be injected as a paste. The impetus for such research is the ageing and more active population – the need to keep quality of life and activity, and to provide materials with longer endurance within the body.
In our biomaterials group the focus is on the synthesis and characterisation of various bioceramics, particularly in the targeted doping of the parent calcium phosphates with the aim of improving the properties, such as solubility, cell interaction, handling, and mechanical properties. Our research extends from basic science and fundamental materials chemistry through to biological testing and commercial application of such materials. The proposed project will be interdisciplinary in nature, allowing the candidate to develop their research skills within this very applied research area.
The focus of the project, therefore, is to synthesise and control the doping of different elements into parent calcium phosphates that will be one or more of the reactant phases of the cement formulations. These will be used in developing new calcium phosphate bone cement formulations. These materials have potential application in fabricating 3D scaffolds for bone tissue engineering and regenerative medicine, or as medical devices. The materials developed will be characterise using X-ray diffraction, Raman and IR spectroscopy, solid state NMR, electron microscopy, surface area and porosity quantification, solubility testing and mechanical testing.
Whilst some chemical knowledge is highly desirable, knowledge of the solid state and a willingness to learn and engage in interdisciplinary research is essential for such work, where chemistry, materials science, physics, engineering, biology and medicine meet.
Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Materials Chemistry, Inorganic Chemistry, Materials Engineering, Biomedical Engineering.
