University of Galway spin-out collaborates with European Space Agency
University of Galway spin-out Aquila Bioscience is collaborating with the European Space Agency (ESA) to develop decontamination technology for safer space exploration.
Traditional antimicrobial measures, while effective on Earth, present significant limitations in space due to potential toxicity, pathogen resistance, and long-term stability concerns. The unique conditions of spaceflight elevate the risk of infectious diseases by altering both human and microbial physiology.
Aquila Bioscience’s approach to pathogen decontamination is informed by an extensive review of International Space Station microbiome research, which identified key pathogens posing health risks in confined space environments. These include viruses, bacteria and fungi that cause respiratory, gastrointestinal, urinary and skin infections.
Prof Lokesh Joshi, founder of Aquila Bioscience and Stokes Professor of Glycosciences at University of Galway, said: “Aquila Bioscience is committed to addressing the critical challenges of pathogen exposure in space. Our pathogen capturing technology aligns with the principles of safety, sustainability and innovation that are essential for the future of space exploration… This collaboration underscores the importance of developing sustainable, non-toxic and effective solutions for challenges associated with space exploration.”
Aquila Bioscience’s pathogen capturing technology (PCT) solution can enhance health and safety protocols for space missions. Unlike traditional antimicrobials that may lead to pathogen mutations, sterilisation tolerance, or antimicrobial resistance (AMR), Aquila Bioscience’s technology provides a safe, effective and eco-friendly alternative that is stable over long periods as space agencies and commercial spaceflight companies strive to ensure the health and safety of their crews.
Prof Joshi said: “The deployment of our pathogen control technology in space missions has the potential to revolutionise decontamination protocols, enhancing the safety and well-being of astronauts while supporting sustainable and responsible space exploration.”
Aquila Bioscience uses a selection of natural protein-carbohydrate molecules on a biodegradable matric that act as ‘molecular-Velcro’, to capture and remove harmful pathogens without damaging human skin or surfaces.
The PCT’s biodegradable composition also addresses critical spaceflight constraints such as payload weight and waste management, ensuring its suitability for long-duration missions.
The solution has been inspired by the knowledge of how nature protects humans from germs encountered on a regular basis, offering a non-toxic alternative to conventional decontamination agents like alcohol, bleach, and ammonium compounds, which are often unsuitable for skin use due to their harshness and potential toxicity.
