Green synthesis of silver nanoparticles by sweet cherry and its application against cherry spot disease

mycolabadmin

Researchers developed a natural, eco-friendly method to fight a fungal disease that damages sweet cherries after harvest. Using tiny silver particles created from cherry fruit extracts, they successfully stopped the growth of harmful Alternaria fungi. This approach offers farmers an environmentally safe alternative to traditional chemical fungicides while protecting cherry crops from rot.

Green synthesis of silver nanoparticles using fermentation extracts from a mangrove soil bacterium: morphological characterization, and antifungal activities against rice blast fungus

mycolabadmin

Researchers developed tiny silver particles made from bacteria found in mangrove soil that effectively kill the fungus causing rice blast disease. These nanoparticles work better than current chemical fungicides and are much safer for the environment and aquatic life. The particles stop the fungus from growing and spreading in rice plants, offering farmers a sustainable alternative to traditional chemical pesticides.

Inhibition of Fusarium oxysporum growth in banana by silver nanoparticles: In vitro and in vivo assays

Researchers tested silver nanoparticles as a potential cure for Fusarium wilt, a serious fungal disease that damages banana crops worldwide. Using laboratory tests and greenhouse experiments with banana plants, they found that silver nanoparticles effectively killed the fungus and reduced disease symptoms by about 68% when applied to plant roots. The study shows that this nanotechnology approach could offer a new way to protect banana plantations from this devastating disease.

Effect of AgNPs on PLA-Based Biocomposites with Polysaccharides: Biodegradability, Antibacterial Activity and Features

mycolabadmin

Scientists created new plastic-like materials made from corn-based PLA combined with silver nanoparticles and natural starches or chitosan. These biocomposites break down in soil while also killing harmful bacteria. The materials showed that adding silver particles didn’t prevent fungi from breaking them down in nature, making them suitable for environmentally-friendly products like food packaging that need to both degrade naturally and prevent bacterial growth.

Harnessing pycnidia-forming fungi for eco-friendly nanoparticle production, applications, and limitations

mycolabadmin

Certain types of fungi can produce tiny metal particles called nanoparticles that have useful properties. These fungi-made nanoparticles can kill bacteria, fight cancer cells, clean pollutants from water and soil, and be used in medicines and agriculture. Unlike traditional chemical methods for making nanoparticles, using fungi is cleaner and safer for the environment, though scientists still need to understand more about how they work and ensure they are safe to use widely.

Synthesis of silver nanoparticles using Eucommia ulmoides extract and their potential biological function in cosmetics

mycolabadmin

Scientists created tiny silver particles using a Chinese medicinal plant extract and found they could help skin look lighter and younger. These particles work by reducing dark pigments and protecting skin from oxidative damage. The nanoparticles were safe at low doses and didn’t harm skin cells, making them promising for use in cosmetic products.

Harnessing pycnidia-forming fungi for eco-friendly nanoparticle production, applications, and limitations

mycolabadmin

Certain fungi called pycnidial fungi can create tiny particles called nanoparticles that are useful in medicine, agriculture, and environmental cleanup. These fungi naturally produce chemicals and enzymes that reduce metal ions into nanoparticles, which have antimicrobial and cancer-fighting properties. While this biological approach is more environmentally friendly than chemical methods, scientists still need to solve challenges like making it work at large scales and ensuring the nanoparticles are safe and stable.

Extracellular Biosynthesis, Characterization and Antimicrobial Activity of Silver Nanoparticles Synthesized by Filamentous Fungi

mycolabadmin

Researchers used three types of common fungi to create tiny silver particles in an environmentally friendly way. These silver nanoparticles were found to effectively kill harmful bacteria and fungal infections. The fungus Cladosporium cladosporoides was the most effective at producing these particles, showing promise for use in medical and health applications.

Effect of AgNPs on PLA-Based Biocomposites with Polysaccharides: Biodegradability, Antibacterial Activity and Features

mycolabadmin

Scientists created new eco-friendly plastic films made from corn-based PLA combined with natural starches and tiny silver particles. These films can break down in soil while also killing harmful bacteria, making them ideal for food packaging. The materials maintained good antibacterial properties even as they slowly degraded in the environment, showing promise as sustainable alternatives to conventional plastics.

Advancing Food Preservation: Sustainable Green-AgNPs Bionanocomposites in Paper-Starch Flexible Packaging for Prolonged Shelf Life

mycolabadmin

Researchers developed an eco-friendly food packaging material by coating paper with corn starch and tiny silver particles created through green chemistry methods. This innovative packaging significantly improved food durability, reducing weight loss in fresh produce like tomatoes and grapes by 6-8% over six days. The material is completely biodegradable and poses no safety concerns, making it a sustainable alternative to traditional plastic packaging.
