Modelling atmospheric plasma processes for biofunctionalization in additive manufacturing


This project will develop multiphysics models of atmospheric pressure plasma systems to engineer interfaces and biofunctionalised scaffolds in 3D bioprinting.  
The Applied Physics and Plasma Surface Engineering group is seeking applications from highly motivated PhD candidates with strong communication skills, a demonstrated ability to work independently, and a desire to make meaningful contribution to state-of-the-art biomedical and plasma technologies. Potential candidates with backgrounds in plasma physics, computational fluid dynamics/finite element modelling, nanotechnology, chemical engineering, mechanical engineering, chemistry, or surface engineering are encouraged to apply. Selected candidates will be supported to apply for suitable scholarships where eligible.  
A complimentary scholarship for this project may be available through a competitive process. To find out more, refer to the Faculty of Science Postgraduate Research Excellence Award and contact Prof Marcela Bilek directly.

Program type



3D bioprinting, also known as biofabrication, promises highly patient-specific disease models and biomedical implants. However, an ability to tailor surface biocompatibility and interfacial bonding between printed components, such as polymers and hydrogels, is currently lacking. We are developing atmospheric pressure plasma processes that can locally activate polymeric surfaces for the reagent-free covalent attachment of proteins and hydrogel in a single-step process at desired locations throughout the printed structures. To develop the process further we need a deep understanding of the mechanisms that underpin the surface activation we observed.
This multidisciplinary project will offer candidates the opportunity to develop and optimise finite element models of the complex physical phenomena occurring within an experimental atmospheric pressure plasma jet. Plasma dynamics will be investigated using drift-diffusion and heavy species transport models to understand the strong spatial and temporal gradients formed during operation, whilst fluid-particle models will be used to monitor atmospheric entrainment in plasma jets. Candidates will work closely with experimentalists to apply the knowledge gained from the modelling to guide atmospheric plasma process design and 3D printing biofunctionalisation experiments.
