Oral Insulin Delivery facilitated by Enteric Coating using Dense Gas Technologies. Insulin dependant diabetes is a rapidly growing disease. The current method for insulin delivery to the patient is by injection, which is inconvenient. Oral delivery of insulin is a more acceptable method. It is proposed to develop a dense gas technique to coat insulin with a pH sensitive polymer to protect it from the acidic environment of the stomach. Insulin can then be released at the high pH of the intestin ....Oral Insulin Delivery facilitated by Enteric Coating using Dense Gas Technologies. Insulin dependant diabetes is a rapidly growing disease. The current method for insulin delivery to the patient is by injection, which is inconvenient. Oral delivery of insulin is a more acceptable method. It is proposed to develop a dense gas technique to coat insulin with a pH sensitive polymer to protect it from the acidic environment of the stomach. Insulin can then be released at the high pH of the intestine when the polymer is dissolved. Particle size control is feasible by dense gas processes by manipulating operating parameters. Advantages include low residual solvent and manufacture at ambient temperatures.Read moreRead less
Synthetic derivatives of capsaicin and gingerols as analgesics acting at the vanilloid receptor. This project aims to prepare alpha-hydroxyketones and gingerol derivatives acting at vanilloid (VR1) receptor with potential analgesic activity. These compounds will be tested for their ability to activate the VR1 receptor, desensitize the receptor and release neuropeptides associated with pain pathways. The development of these novel compounds will contribute towards understanding the mechanisms of ....Synthetic derivatives of capsaicin and gingerols as analgesics acting at the vanilloid receptor. This project aims to prepare alpha-hydroxyketones and gingerol derivatives acting at vanilloid (VR1) receptor with potential analgesic activity. These compounds will be tested for their ability to activate the VR1 receptor, desensitize the receptor and release neuropeptides associated with pain pathways. The development of these novel compounds will contribute towards understanding the mechanisms of VR1 receptor activation and provide information on how the VR1 receptor is regulated. We will determine and compare neurotoxicity of these compounds to capsaicin which is known to possess neurotoxic activity. The outcome of this project may result in effective agents for better pain management.

Drug Delivery Devices : Hydrogels manufactured utilising Dense Gas Technologies. Many drugs are rapidly eliminated from the human body, and would benefit from being released over a long period of time. In this study, formulations to deliver drugs will be developed, using hydrogels: highly cross-linked, water saturated polymers. The polymers to be investigated are based on ingredients suitable for ingestion. Hydrogels are in common use as external therapeutic devices, such as contact lenses or wo ....Drug Delivery Devices : Hydrogels manufactured utilising Dense Gas Technologies. Many drugs are rapidly eliminated from the human body, and would benefit from being released over a long period of time. In this study, formulations to deliver drugs will be developed, using hydrogels: highly cross-linked, water saturated polymers. The polymers to be investigated are based on ingredients suitable for ingestion. Hydrogels are in common use as external therapeutic devices, such as contact lenses or wound dressings. However, hydrogels are not commonly in use as ingested drug delivery devices due to problems with the existing technologies, such as toxicity of ingredients. These problems will be addressed in this study.Read moreRead less
Carbon Dioxide: Solvent, Carrier and Reagent, for novel polymer networks with controlled nano-architectures. The proposed environmentally friendly technology has broad applications for improving properties of various polymeric matrices used for biomedical applications. The process developed would value-add for manufacturing biomedical polymeric devices in Australia with licensing of existing fabrication methods as a best option. Moreover, the leading-edge polymer technology developed would mini ....Carbon Dioxide: Solvent, Carrier and Reagent, for novel polymer networks with controlled nano-architectures. The proposed environmentally friendly technology has broad applications for improving properties of various polymeric matrices used for biomedical applications. The process developed would value-add for manufacturing biomedical polymeric devices in Australia with licensing of existing fabrication methods as a best option. Moreover, the leading-edge polymer technology developed would minimise the organic solvent consumption and will attract business from international polymer and biotechnology companies for production of implant and drug delivery devices. The development of world-class research provides Australia with recognition as a world leader in the field and broadens the knowledge based of Australian scientist and engineers.Read moreRead less
