This research explores how fungi can be used to produce metal-containing nanoparticles in an environmentally friendly way. Instead of using harsh chemicals and high energy processes, fungi can naturally create and stabilize nanoparticles through their normal biological processes. This has important implications for developing more sustainable manufacturing methods. Key impacts on everyday life: – More environmentally friendly production of nanoparticles used in consumer products – Potential for new medical treatments using biologically-produced nanoparticles – Development of more sustainable industrial processes – Improved agricultural applications using naturally-derived nanomaterials – Reduced environmental impact from nanoparticle manufacturing
