Scientists studied how to enhance the medicinal properties of chaga mushroom using tiny metal particles and laser light. They found that adding silver, iron, or magnesium nanoparticles to growing mushroom cultures increased biomass production. When combined with laser treatment, these nanoparticles dramatically boosted the production of beneficial compounds like polysaccharides, flavonoids, and melanin pigments that have health benefits including antioxidant and immune-boosting properties.
