Engineered Metal Nanoparticles: A Possible Small Solution to Big Problems Associated with Toxigenic Fungi and...

Area of Science:

• Food Science
• Nanotechnology
• Mycology

Background:

• Mycotoxins produced by fungi like Aspergillus and Fusarium contaminate staple foods, posing significant public health and economic risks.
• Climate change exacerbates fungal adaptation to environmental stresses, increasing the challenge of controlling toxigenic fungi.
• Development of novel antifungal and anti-mycotoxin strategies is a priority for food safety.

Purpose of the Study:

• To review the antifungal and anti-mycotoxin potential of metal nanoparticles (NPs) and metal oxide nanoparticles.
• To assess the efficacy of silver, copper, copper oxide, and zinc oxide NPs against foodborne fungi and mycotoxins.
• To identify challenges and future directions for NP application in the food industry.

Main Methods:

• Literature review synthesizing studies on metal and metal oxide nanoparticles.
• Analysis of NP synthesis methods, definitions, and regulatory aspects.
• Evaluation of existing research on NP effects on fungal growth and mycotoxin production.

Main Results:

• Metal nanoparticles (silver, copper) and metal oxide nanoparticles (copper oxide, zinc oxide) demonstrate high reactivity and stability.
• These NPs show potential in combating foodborne fungal contamination and mycotoxin production.
• Existing studies indicate a need for simultaneous analysis of NP effects on fungal growth and mycotoxin levels.

Conclusions:

• Metal and metal oxide nanoparticles present a promising avenue for controlling foodborne fungal risks.
• Significant challenges remain regarding biosafety, consumer acceptance, and standardization for food industry implementation.
• Further research is needed to bridge methodological gaps and ensure safe and effective application of NPs.
