Synthesis of nanoparticles by fungi. Throughout human history, fungi have been utilized as a source of food and harnessed to ferment and preserve foods and beverages. In the 20th century, humans have learned to harness fungi to protect human health ( antibiotics, anti-cholesterol statins, and immunosuppressive agents), while industry has ...
Copper and titanium dioxide nanoparticles are less commonly employed in antimicrobial polymers than silver nanoparticles. [1] Copper nanoparticles embedded into polypropylene nanocomposites have demonstrated the ability to kill 99.9% of bacteria. [1] Titanium dioxide is a nontoxic material with antimicrobial activity that is photo-activated. [3]
Chitosan proves to be effective against bacteria, viruses, and fungi, however it is more effective against fungi and viruses than bacteria. The positively charged chitosan nanoparticles interact with the negatively charged cell membrane, which causes an increase in membrane permeability and eventually the intracellular components leak and rupture.
Nanobacterium (/ ˌnænoʊbækˈtɪəriəm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌnænoʊbækˈtɪəriə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally accepted lower limit for life ...
Nanotechnology is the process of manipulating atoms on a nanoscale. [1] In nanotechnology, nanomembranes are used with the purpose of softening the water and removal of contaminants such as physical, biological and chemical contaminants. There are variety of techniques in nanotechnology which uses nanoparticles for providing safe drinking water ...
Phoma epicoccina Punith. Toruloidea tobaica Svilv. Epicoccum nigrum is a species of fungus in the phylum Ascomycota. A plant pathogen and endophyte, it is a widespread fungus which produces coloured pigments that can be used as antifungal agents against other pathogenic fungi. The fluorescent stain epicocconone is extracted from it.
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1][2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. [2]: 394 At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
A nanotechnological application of D. radiodurans in the synthesis of silver [36] and gold [37] nanoparticles has also been described. Whereas chemical and physical methods to produce these nanoparticles are expensive and generate a huge amount of pollutants , biosynthetic processes represent an ecofriendly and cheaper alternative.
