Engineering better sprays for leaf coating: from drop impact to retention. This proposal aims to understand the performance of a unique rheological modifier that can enable an order of magnitude increase in coating efficiency for aerosol sprays while not affecting the quality of droplet formation during spraying. The effect occurs via a dispersed network of fibrous particles in water, providing a weak but useful ability to coat surfaces by responsively adjusting its structure. The material is ex ....Engineering better sprays for leaf coating: from drop impact to retention. This proposal aims to understand the performance of a unique rheological modifier that can enable an order of magnitude increase in coating efficiency for aerosol sprays while not affecting the quality of droplet formation during spraying. The effect occurs via a dispersed network of fibrous particles in water, providing a weak but useful ability to coat surfaces by responsively adjusting its structure. The material is expected to enable a broad array of applications, from agricultural treatments to nasal sprays, by exhibiting responsive behaviour at concentrations much lower than conventional modifiers require. The project will study the responsiveness of the system in single droplet, spray, and coating form as well as an active delivery system.Read moreRead less
Gene regulation by retroelement encoded natural antisense transcripts. Genetic information underpins all life on earth and is processed to make proteins, which determine the characteristics of an organism. However, only about 2% of our whole genome is made up of genes that encode proteins; the other 98% is non-coding and its function remains poorly understood. Aims and Significance: This proposal aims to utilise cutting edge genomic technologies to generate new knowledge about how the non-coding ....Gene regulation by retroelement encoded natural antisense transcripts.

However, only about 2% of our whole genome is made up of genes that encode proteins; the other 98% is non-coding and its function remains poorly understood. Aims and Significance: This proposal aims to utilise cutting edge genomic technologies to generate new knowledge about how the non-coding genome regulates the expression of protein coding genes. Expected Outcomes and Benefits: This proposal will provide novel targets and methodology for gene modulation with broad applications from biology to environmental sciences.Read moreRead less
Plant plasters: Efficient spray micro-coatings for plant delivery. This proposal will study and apply recently-discovered methods of strongly attaching beneficial chemicals to plant leaves, stalks, and fruit. The materials have an unusually good ability to stick to crop plants and deliver herbicide or pesticide active ingredients more efficiently than standard additives, without toxicity. Recent findings have shown significant health risks from commercial herbicide additives and their run-off in ....Plant plasters: Efficient spray micro-coatings for plant delivery. This proposal will study and apply recently-discovered methods of strongly attaching beneficial chemicals to plant leaves, stalks, and fruit. The materials have an unusually good ability to stick to crop plants and deliver herbicide or pesticide active ingredients more efficiently than standard additives, without toxicity. Recent findings have shown significant health risks from commercial herbicide additives and their run-off into vulnerable ecosystems like the Great Barrier Reef. This project will explain the unusually effective, but simple, adhesion and delivery performance, incorporate the new additives into commercially-relevant formulations for our industrial partner, and work to deliver the materials at relevant manufacturing scales.Read moreRead less
Clay nanoparticle-facilitated RNAi for non-transgenic modification of crops. This project aims to define the most effective spray formulations, consisting of clay nanoparticles and induced RNA interference (RNAi) to manipulate gene expression in plants. Topical application of double-stranded RNA (dsRNA) for RNAi represents an attractive alternative to genetically engineered crops. However, naked dsRNA is unstable and is not efficiently taken up by plants. For these reasons, topical application o ....Clay nanoparticle-facilitated RNAi for non-transgenic modification of crops. This project aims to define the most effective spray formulations, consisting of clay nanoparticles and induced RNA interference (RNAi) to manipulate gene expression in plants. Topical application of double-stranded RNA (dsRNA) for RNAi represents an attractive alternative to genetically engineered crops. However, naked dsRNA is unstable and is not efficiently taken up by plants. For these reasons, topical application of dsRNA has thus far produced only modest induction of RNAi in plants. Nanoparticle-facilitated manipulation of gene expression in plants will enable sustainable clean green strategies for protecting crops from diseases. This project will result in improved crop protection and productivity and boost the export potential of Australian crops.Read moreRead less
Portable instrument for quantification and genotyping of Cryptosporidium . Cryptosporidium is a parasitic protozoan, causing more than 48,000 deaths in children under 5 and 7.2 million disability-adjusted-life-years globally. A low-cost device that rapidly detects the parasite in drinking and recreational water is needed to enable effective disease management practices. Partnering with Advanced Universal Diagnotik, Seqwater, ALS Water and Gold Coast Water, this project aims to develop a novel de ....Portable instrument for quantification and genotyping of Cryptosporidium . Cryptosporidium is a parasitic protozoan, causing more than 48,000 deaths in children under 5 and 7.2 million disability-adjusted-life-years globally. A low-cost device that rapidly detects the parasite in drinking and recreational water is needed to enable effective disease management practices. Partnering with Advanced Universal Diagnotik, Seqwater, ALS Water and Gold Coast Water, this project aims to develop a novel device, comprising advanced microfluidics and biosensing technology for parasite quantification, genotyping and viability analysis. Expected outcomes are improved Cryptosporidium management, risk prediction, and rapid mitigation of impending outbreaks. The proposed platform has a great potential for detecting other pathogens.Read moreRead less
