Development of a Prothrombogenic Bone Graft Substitute. The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction.

The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from the blood. This response will lead to the formation new viable tissue and eventually bone. Such a material will cause faster bone healing, less pain from graft sites, shorter hospital stays and shorter waiting lists. Read moreRead less
Attachment of Growth Factors to Pure, Plasma Modified and Coated Titanium Substrates. Titanium and its alloys are routinely used as medical and dental implants. Despite coating with hydroxyapatite, a material well known to improve implant fixation, many such implants fail because of lack of strong integration with bone. This proposal aims at achieving long-term stability of titanium implants through their surface modification and subsequent attachment of growth factors. The use of latter has alr ....Attachment of Growth Factors to Pure, Plasma Modified and Coated Titanium Substrates. Titanium and its alloys are routinely used as medical and dental implants. Despite coating with hydroxyapatite, a material well known to improve implant fixation, many such implants fail because of lack of strong integration with bone. This proposal aims at achieving long-term stability of titanium implants through their surface modification and subsequent attachment of growth factors. The use of latter has already been shown to help bone-implant integration. Successful project implementation will provide titanium implant surfaces that will help achieve speedier and improved implant fixation with long-term stability. Knowledge, expertise and techniques developed will help the industry partner expanding its research base and business and generating wealth in Australia. Training of world-class research students in the emerging field of biotechnology will be another major outcome.Read moreRead less
A novel electrospraying technology platform for controlled and targeted growth factor delivery. This project will develop a new growth factor delivery strategy to stimulate bone regeneration. The project will utilise the technique of electrospraying to create small dissolving polymer microspheres containing bone-relevant growth factors, which are released gradually as the polymer degrades after implantation into a bone defect site to promote healing.
The development of new scaffolds for bone repair comprising polycaprolactone and strontium-substituted bioactive glasses. The drive to develop bone grafts to fill major gaps in the skeleton, whilst circumventing the need to use permanent implants has led to a major research thrust towards developing biomaterials for bone-tissue engineering. The project will develop scaffolds with highly osteoconductive bioactive glasses in a polymer matrix for bone regeneration applications.
Bone tissue engineering using innovative tubular dual-layered nanofiber meshes. Lifetime risks for long-bone fractures in Caucasians over the age of 50 are 17 per cent for women and 6 per cent for men. A clear therapeutic need exists to address the ever-increasing problems of diminished productivity and reduced quality of life associated with bone disorders as the population ages. To address this challenge, the project’s multidisciplinary, international team will develop technologies to heal tib ....Bone tissue engineering using innovative tubular dual-layered nanofiber meshes. Lifetime risks for long-bone fractures in Caucasians over the age of 50 are 17 per cent for women and 6 per cent for men. A clear therapeutic need exists to address the ever-increasing problems of diminished productivity and reduced quality of life associated with bone disorders as the population ages. To address this challenge, the project’s multidisciplinary, international team will develop technologies to heal tibial defects. Furthermore, it will establish Australia's prominence in the tissue engineering field, training the next generation of young scientists and engineers. This technology will be of interest to numerous research groups and companies worldwide and will foster international collaboration, placing Australia at the forefront of this emerging field.Read moreRead less
