Silver nanoparticles, with a particle size of about 25\nnm, can strongly inhibit and kill dozens of pathogenic microorganisms such as\nEscherichia coli, Neisseria gonorrhea, and Chlamydia trachomatis, and there is\nno worry about drug resistance. All kinds of daily necessities made of\nnanosilver have a good antibacterial effect.<\/p>\n\n\n\n<p>Key\nfeatures:<\/p>\n\n\n\n<p>1.\nParticle size is less than 100nm, generally between 25-50nm.<\/p>\n\n\n\n<p>2. The\nproperties of the silver nanoparticles are directly related to its particle\nsize.<\/p>\n\n\n\n<p>3. The\nsmaller the particle size, the stronger the sterilization performance.<\/p>\n\n\n\n<p>Antibacterial\nproperties<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Broad-spectrum antibacterial<\/li><\/ul>\n\n\n\n<p>Silver\nnanoparticles directly enter the bacteria and combine with the oxygen metabolism\nenzyme (-SH) to suffocate the bacteria. Thus, the silver nanoparticle is able\nto kill most of the microorganisms that come into contact with them. Generally,\nan antibiotic can kill about 6 kinds of pathogens, while a nanosilver can kill\nhundreds of pathogenic microorganisms including bacteria, fungi,\ntrichomoniasis, mycoplasma\/chlamydia, and Neisseria gonorrhoeae.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Strong sterilization<\/li><\/ul>\n\n\n\n<p>According\nto research, silver ions can kill more than 650 kinds of bacteria in a few\nminutes even in a low concentration.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Strong permeability<\/li><\/ul>\n\n\n\n<p>Silver\nnanoparticles have super permeability and can quickly infiltrate into\nsubcutaneous 2 mm to sterilize. Silver nanoparticles have a good bactericidal\neffect on deep tissue infections caused by common bacteria, stubborn bacteria,\ndrug-resistant bacteria, and fungi.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Repair and regeneration<\/li><\/ul>\n\n\n\n<p>Nanosilver\ncan contribute to wound healing, promote the repair and regeneration of damaged\ncells, and improve the microcirculation of tissues around the wound.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Long-lasting antimicrobial activity<\/li><\/ul>\n\n\n\n<p>Silver\nnanoparticles can gradually release silver ions in the human body to achieve\nlong-lasting antibacterial effects.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>No drug resistance<\/li><\/ul>\n\n\n\n<p>The\nsilver nanoparticle is a non-antibiotic bactericide, which can quickly and\ndirectly kill bacteria before they reproduce. Therefore, the offspring with\ndrug resistance cannot be produced.<\/p>\n\n\n\n<p>Applications<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Superconductivity<\/li><\/ul>\n\n\n\n<p>Using a\nlight sintered body made of 70nm silver powder as a heat exchange material can\nmake the working temperature of the refrigerator reach 0.01-0.003K, and the\nefficiency is 30% higher than that of traditional materials. The introduction\nof nano-silver into the synthesis of superconducting materials has greatly\npromoted the development of the field of superconductivity.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Catalysis<\/li><\/ul>\n\n\n\n<p>Silver\nnanoparticles can be used as catalysts for a variety of reactions. In the\nprocess of laser dissociation of polystyrene and polymethyl methacrylate, the\naddition of silver nanoparticles leads to the carbonization of the polymer and\ninduces graphitization at the interface. At the same time, the interface\nreaction between silver nanoparticles and polymethyl methacrylate changes the\ntransformation mode of laser energy and weakens the laser carbonization effect.\nIn a word, the addition of silver nanoparticles changes the absorption and\nconversion of laser energy in the polymer system, which leads to the change of\nlaser dissociation.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Surface enhanced Raman spectroscopy<\/li><\/ul>\n\n\n\n<p>Silver\nnanoparticles can be used as the matrix of surface enhanced Raman spectroscopy\n(SERS). According to the electrical properties of molecules, choosing silver\nnanoparticles with different electrical properties can obtain strong SERS\nspectra, and then expand the research scope of SERS. At the same time, due to\nthe ultrafast nonlinear optical response near the surface plasma oscillation\nabsorption peak of silver nanoparticles, scientists have found that large\nnonlinear polarizability can be obtained by doping silver nanoparticles into\nsemiconductors or insulators. This characteristic can be used to make\noptoelectronic devices, such as optical switches and color filters of advanced\noptical devices.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Textile<\/li><\/ul>\n\n\n\n<p>As\npeople&#8217;s requirements for textile products increase, nanosilver is increasingly\nbeing used in functional fabrics, making the fabrics have multiple functions\nsuch as moisture absorption, perspiration, and antibacterial. The application\nprospect of nano-silver in the textile industry will become wider and wider.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The silver nanoparticle is a metallic silver substance with nanometer particle size.
