Fungal pathogens continue to pose a significant threat to public health, prompting the World Health Organization (WHO) to highlight their severity. The limitations of current antifungal treatments, such as slow action and the emergence of drug resistance, necessitate the development of innovative solutions. Researchers Hyun (Michel) Koo and Edward Steager from the University of Pennsylvania have joined forces to explore the use of microrobots in combating fungal infections. Their collaborative efforts have led to the development of nanozyme microbots, capable of precisely targeting and swiftly eliminating fungal pathogens, specifically Candida albicans.
Harnessing the Power of Nanozymes: Nanozymes, which are nanoscale particles possessing catalytic and magnetic properties, offer a promising avenue for treating infections. Koo and Steager leveraged iron oxide particles to create nanozyme microrobots that can be manipulated by magnetism. Similar to the enzyme peroxidase found in the human body, these iron oxide nanoparticles initiate a reaction that breaks down hydrogen peroxide into reactive oxygen species. These oxygen species are highly destructive to fungal cells, facilitating their elimination. By employing different motion patterns, such as vibration, rolling, gliding, or dabbing, the researchers directed the nanozymes to target specific infection sites.
