Biomolecular activity modulated by interaction with nanostructures. Nanotechnological methods are able to reliably fabricate artificial nanostructures with dimensions similar to those of large biomolecules (a few to tens of nanometers). This study focuses on the interaction of artificial nanostructures with biomolecules such as proteins and DNA, and will enable scientists to better understand biomolecular recognition and binding events, which are central to all biological processes. The underst ....Biomolecular activity modulated by interaction with nanostructures. Nanotechnological methods are able to reliably fabricate artificial nanostructures with dimensions similar to those of large biomolecules (a few to tens of nanometers). This study focuses on the interaction of artificial nanostructures with biomolecules such as proteins and DNA, and will enable scientists to better understand biomolecular recognition and binding events, which are central to all biological processes. The understanding gained can then be used to design biomimetic surfaces for use in health monitoring and medical diagnostic devices with improved sensitivity, robustness and portability, thereby providing significant benefits to the health sector.Read moreRead less
Bacterial cell behaviour in micro/nano-confined environments. The project aims to progress the understanding of the mechanisms of marine bacteria biofilm formation and surface-modulated metabolic response. We will adjust the surface characteristics of photopolymers (as ?model? surfaces) and probe the bacterial response to surfaces, passively with micro/nano-fabricated structures and Atomic Force Microscopy; and actively with optical manipulation of single cells. The results will contribute to th ....Bacterial cell behaviour in micro/nano-confined environments. The project aims to progress the understanding of the mechanisms of marine bacteria biofilm formation and surface-modulated metabolic response. We will adjust the surface characteristics of photopolymers (as ?model? surfaces) and probe the bacterial response to surfaces, passively with micro/nano-fabricated structures and Atomic Force Microscopy; and actively with optical manipulation of single cells. The results will contribute to the fundamental knowledge regarding central biological phenomena -down to single-cell processes- as well as on applied knowledge regarding the manufacturing of antimicrobial surfaces that mimic natural bactericide processes, with larger implications on biomedical practice, and environmental, civil, mining and manufacturing industrial applications.Read moreRead less
A biophotonics-based approach to the study of cell-mechanics. This study will help to promote and maintain good health. There is a connection between diseases such as arthritis and osteoporosis and cell mechanics. Our study will provide insight into cell mechanics, thereby helping to understand the pathophysiology of these diseases. The study is relevant to tissue engineering. There is ongoing research on mechanical conditioning of tissue substitutes. Understanding cell mechanics will help to op ....A biophotonics-based approach to the study of cell-mechanics. This study will help to promote and maintain good health. There is a connection between diseases such as arthritis and osteoporosis and cell mechanics. Our study will provide insight into cell mechanics, thereby helping to understand the pathophysiology of these diseases. The study is relevant to tissue engineering. There is ongoing research on mechanical conditioning of tissue substitutes. Understanding cell mechanics will help to optimise conditioning protocols, thereby improving the properties of engineered tissue.
During this study we will develop optical tools that have applications in the life sciences, in the development of advanced materials and in nanotechnology. Our project will promote Australian research in these fields.
