This project will lead to the development of new biodegradable biomaterials ideally suited to many applications in drug delivery and tissue engineering. The understanding of their properties will be built on comprehensive models for diffusion of molecules through the material. The availability of these new biomaterials will facilitate future developments in drug delivery, and will ultimately lead to improved medical outcomes in many areas such as tissue and bone regeneration. The materials designed in this project will help position the Australian biotechnology and pharmaceutical industries to take advantage of the more than $100B USD market (US alone; growth ~ 10% p.a.) in drug delivery.Read moreRead less
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
New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriat ....New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriate rigidity and toughness, and stimulate better bone growth at the interface. In this way the implant should be much longer lasting and the need for undesirable revision surgery reduced. The processing technique proposed could also be a useful platform coating technology in a number of other industries.Read moreRead less
New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high tec ....New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high technology industries, as well as in harsh environments. Because we will be able to manipulate the structure and observe property changes, it should also give us a greater insight into the adhesion mechanisms used by many small animals and bugs.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
Feasibility Studies of Using AC Electrospraying for Biomaterials Synthesis. The proposed interdisciplinary research is anticipated to benefit workers in academia and industry as well as clinicians and patients. Given the demand for point-of-care drug delivery, micro/nano-encapsulation and biomaterials synthesis, the research will be beneficial to the pharmaceutical industry and spin-off/start-up microfluidic businesses interested in commercially developing these devices.

Given the demand for point-of-care drug delivery, micro/nano-encapsulation and biomaterials synthesis, the research will be beneficial to the pharmaceutical industry and spin-off/start-up microfluidic businesses interested in commercially developing these devices. It is intended that the work will improve quality of life by advancing biomaterials technology and by making medical treatment more readily accessable, portable and more efficient. For patients, the proposed drug delivery device can help prevent sudden initial bursts of dose during administration, which could potentially have fatal consequences.Read moreRead less
