A survey conducted by the Universidad Nacional de Colombia Unal showed that: Mushroom “caps” found to be up to 100 nanometers with potential In fields such as medicine and agriculturethanks to the fact that they interact effectively with cells and tissues.
With innovative enzymes and chemicals, these mushrooms offer improved treatments for pathogens dad and diseases such as cancer. Although there are an estimated 300,000 species in the country, only 2.4% of the total are known.

Inspired by these results, chemist Karen Daniela Mayne of the research team explored whether mushrooms with “caps” also had this ability, and obtained promising results.
“Initially, the enzymatic activity of nitrate reductase was evaluated and used as a reference for its possible correlation with nanoparticle-forming ability.. In this test, nitrate ions are induced by providing them in the fungal growth medium and are reduced to nitrite by the fungus. The reagent is added to the excess liquid of the medium in which the fungus grows (called spent medium), It appears reddish in the presence of nitrite. Subsequently, fungi with nitrate reductase ability appear magenta,” he added.
The key to its effectiveness lies in the production nanoparticles Silver is produced through the reduction process of silver ions (Silver+). NitaseReductase reduces silver ions into nanoparticles, critical for developing advanced treatments.
Six fungi species provided by the University of Los Llanos were evaluated. The featured species Hexagonia papyracea became the protagonist of this study due to its excellent performance. andformcuriousoffananyoneleafbigandSlim, thisbacteriaprovedyesleaderexistthisProductionofNanoparticles.
”The average size of silver nanoparticles obtained from Hexagonia papyracea is 18.2 nm. Regarding performance, Obtaining numerical data is complicated because it is impossible to know the exact number of nanoparticles obtained with the technique used,” he said.
The process involves growing the biomass in a broth containing nitrates, which are essential for enzymatic action. A few days later, little thingsparticlescorrespondingarrivebacteriaheanalyzedexistASpectrophotometer, revealThatSpeciesyescapableofProductionthisvaluablenanoparticles.
“The main challenge is observing the enzymatic activity of nitrate reductase in the induction assay. This was done twice, the first time the fungus was grown for six days, as no enzymatic activity was observed, so the second time, the growth time was 15 days, where enzymatic induction of H. papyrus was evident. ” he commented.
Hexagonia species perform well at a pH of 10, focus 2.5 millimoles of silver ions and a temperature of 25°C mark the effect on this fungus.
