Green-Synthesized Nanomaterials from Edible and Medicinal Mushrooms: A Sustainable Strategy Against Antimicrobial...

Antimicrobial resistance (AMR) poses an escalating global health crisis, projected to cause up to 10 million deaths annually by 2050. Conventional antibiotics are increasingly ineffective due to microbial adaptation, overuse, and disruption of gut microbiota. Nanotechnology offers promising alternatives, but traditional nanoparticle synthesis often relies on toxic chemicals and energy-intensive processes. This review explores mushroom-derived nanoparticles (myco-NPs) as sustainable, eco-friendly antimicrobials. Edible and medicinal mushrooms contain bioactive compounds, including polysaccharides, flavonoids, and proteins, that act as reducing and stabilizing agents in nanoparticle biosynthesis. Myco-NPs exhibit antimicrobial activity through membrane disruption, oxidative stress, immune modulation, and biofilm inhibition, while also demonstrating synergistic effects with antibiotics and potential roles in regulating the gut microbiota. Recent advances highlight their potential applications in medicine, food safety, and environmental protection. However, challenges remain regarding standardization, safety evaluation, and large-scale production. We emphasize interdisciplinary collaboration as essential to translating mushroom-based nanotechnology into effective clinical and industrial solutions.
