The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. [2][3][4] Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. [5][6][7] The limited evidence available shows that silver coatings on endotracheal breathing tubes may ...
Copper alloy surfaces have intrinsic properties to destroy a wide range of microorganisms.In the interest of protecting public health, especially in healthcare environments with their susceptible patient populations, an abundance of peer-reviewed antimicrobial efficacy studies have been conducted in the past ten years regarding copper's efficacy to destroy E. coli O157:H7, methicillin ...
Gargling, nasal rinses, and inhalation. Inhaling bleach or other disinfectants is dangerous and will not protect against COVID-19. They can cause irritation and damage to tissues, including the eyes. They are poisonous and WHO has warned not to take it internally and to keep it out of the reach of children.
The size difference causes the difference in colors. Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [ 1 ] The colloid is coloured usually either wine red (for spherical particles less than 100 nm) or blue-purple (for larger spherical particles or nanorods). [ 2 ]
Paul Karason (November 14, 1950 – September 23, 2013) was an American from Bellingham, Washington, whose skin was a purple-blue color. [1] Karason was fair skinned and freckled until the early 1990s. His skin turned blue after he began taking a homemade colloidal silver treatment and rubbing a silver preparation on his skin in an attempt to ...
A copper nanoparticle is a copper based particle 1 to 100 nm in size. [1] Like many other forms of nanoparticles, a copper nanoparticle can be prepared by natural processes or through chemical synthesis. [2] These nanoparticles are of particular interest due to their historical application as coloring agents and the biomedical as well as the ...
Copper is an essential trace element that is vital to the health of all living things (plants, animals and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes. Also, in humans, copper helps maintain the nervous system, immune system, brain development, and activates genes, as well as ...
Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or to silver dust. [1] The most dramatic symptom of argyria is that the skin turns blue or blue-gray. It may take the form of generalized argyria or local argyria. Generalized argyria affects large areas over much of the visible surface ...
