On the cover of Plasma Processes and Polymers
Congratulations to Argha Chakraborty on his brilliant artwork on the cover of Plasma Processes and Polymers.
The artwork illustrates the concept for his recently published article.

New Publication: Plasma-activated water’s potential contribution to ‘One Health’
Plasma-activated water’s potential contribution to ‘One Health’
Abstract
Foodborne pathogens cause a major burden to public health and the economy, costing A$2.44 billion, and causing 48,000 hospitalisations annually in Australia. With an increasing global impact of foodborne illnesses and the emergence of antibiotic-resistant pathogens, new decontamination technologies should consider the One Health approach to human, animal and environmental health. This review explores the application of plasma-activated water (PAW) as a novel sanitisation method. We discuss the implications of adopting PAW as an environmentally friendly and cost-effective sanitiser through a multidisciplinary One Health perspective. The findings underscore the promising role of PAW in mitigating foodborne pathogens, offering a holistic solution that aligns with the principles of One Health for enhanced food safety and public health.
New Publication: A Review of the Current and Future Prospects for Producing Bioplastic Films Made from Starch and Chitosan
Abstract
This review presents a summary of plastic films made from two abundant natural polymers, starch and chitosan. Films possess many useful attributes such as transparency, good physical strength, and barrier properties. Modifications are being investigated to improve the properties of the product such as reinforcement with nanoparticles, strengthening by cross-linking, and applying surface coatings to improve interfacial properties. We provide perspectives on the use of starch chitosan films as a biobased, biodegradable food packaging material. Additionally, a detailed life-cycle assessment compares the production of chitosan-based polymers to other bioplastics and petroleum-based alternatives. Finally, we predict which factors will be important in the future for making the production of chitosan films economically and environmentally sustainable.
Sept 29, 2021: Outcomes of Fungus Olympics published in PLoS ONE (Sept 29, 2021)
I had the pleasure of contributing to a research article which describes the results of the Fungus Olympics competition that I previously wrote about.
The article was published in PLoS ONE and can be found here.

Updating Blog 2023
It’s been quite a while since I’ve updated the blog and I’ve missed capturing some of the important updates.
Starting after this, I’ll retroactively be posting updates that I’ve summarised for the past little while.

After uploading this presentation, I realised that one point which may not have been clear is about the potential applicability of the antifungal surface coating. The covalently-attached antifungal surface coatings would be surface active and best applied to implantable medical devices as a preventative measure, but not as a way of eliminating or breaking up established biofilms when infections have already been established.

On slide 3 I showed the microfluidic device from Prof Daniel Irimia, but failed to give his affiliation. Prof Irimia is researcher and Deputy Director at Massachusetts General Hospital and Harvard Medical School, and organiser of the Fungus Olympics, an event in which my lab participated. You can read more about my involvement in the Fungus Olympics here.
