Tissue engineering and medical implants hold great potential to restore missing tissue functions in the human body, improve screening of new and personalised drugs, and even potentially allow us to grow meat for food in the laboratory. Engineering plays many roles in efforts to achieve these outcomes. A key aspect is the design of biomaterials that can interact with biological cells and tissues in ways that promote the desired tissue development and functions.

Tissue engineering uses biomaterials to mimic the natural tissue microenvironments of cells, act as scaffolding for cell attachment and migration, deliver bioactive signals, and provide space for tissue growth. Optimal design of biomaterial constructs and tissue engineering processes relies on insights into the complex cell and tissue requirements during tissue regeneration, their interactions with biomaterials and how these change over time during development of tissues. The mechanical properties and 3D arrangement of cells and tissues are important to their function and are used as a basis for the design of biomaterial polymer constructs for our research on cell culture in vitro and engineering of soft vascularised tissues in vivo.

A further challenge of using biomaterials in the body is the risk of infection, particularly as bacteria are increasingly developing resistance to conventional antibiotics. Professor O'Connor and her colleagues are developing antimicrobial biomaterials using nanoparticles that can attack bacteria via multiple mechanisms to prevent infections that can otherwise lead to the failure of medical implants and tissue engineering. By combining physical, chemical and biological factors in the design of biomaterial constructs, they aim to enhance the performance of tissue engineering and medical devices.

This event is intended for the general public and is free to attend. Light refreshments will be served from 5.00pm.
