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 ...
Silver nanoparticles can undergo coating techniques that offer a uniform functionalized surface to which substrates can be added. When the nanoparticle is coated, for example, in silica the surface exists as silicic acid. Substrates can thus be added through stable ether and ester linkages that are not degraded immediately by natural metabolic ...
Characterization of nanoparticles. Nanoparticles differ in their physical properties such as size, shape, and dispersion, which must be measured to fully describe them. The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,.
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter. This definition of nanotechnology includes all types of research and technologies that deal ...
Deinococcus radiodurans. Brooks & Murray, 1981. Look up Deinococcus or radiodurans in Wiktionary, the free dictionary. Deinococcus radiodurans is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile.
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.
Chitosan / ˈkaɪtəsæn / is a linear polysaccharide composed of randomly distributed β- (1→4)-linked D -glucosamine (deacetylated unit) and N -acetyl- D -glucosamine (acetylated unit). It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide. [ 1 ][ 2 ] Chitosan has a ...
Mechanical deformation of the cell membrane can be achieved by a number of experimental interventions, including magnetic actuation of nanoparticles. An example of this is the control of calcium influx of axons and boutons within neural networks. [65] Note that this is not an indication of 'magnetic stimulation' of mechanosensitive channels.
