Gold nanoparticles in chemotherapy and radiotherapy is the use of colloidal gold in therapeutic treatments, often for cancer or arthritis. Gold nanoparticle technology shows promise in the advancement of cancer treatments. Some of the properties that gold nanoparticles possess, such as small size, non-toxicity and non-immunogenicity make these ...
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 ]
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 ...
Gold-containing drugs are pharmaceuticals that contain gold. Sometimes these species are referred to as "gold salts". "Chrysotherapy" and "aurotherapy" are the applications of gold compounds to medicine. [1] Research on the medicinal effects of gold began in 1935, [2] primarily to reduce inflammation and to slow disease progression in patients ...
Immunogold labeling or immunogold staining (IGS) is a staining technique used in electron microscopy. [2] This staining technique is an equivalent of the indirect immunofluorescence technique for visible light. Colloidal gold particles are most often attached to secondary antibodies which are in turn attached to primary antibodies designed to ...
Polyvalent DNA gold nanoparticles. Polyvalent DNA gold nanoparticles, now more commonly referred to as spherical nucleic acids, [1] (Fig. 1) are colloidal gold particles densely modified with short (typically ~30-mer or less), highly oriented, synthetic DNA strands. They were invented by Chad Mirkin et al. at Northwestern University in 1996. [2]
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
The colloidal gold protein assay is a highly sensitive biochemical assay for determining the total concentration of protein in a solution (~0.1 ng/μL to 200 ng/μL). [1] It was first described in 1987 by two groups who used commercially available "Aurodye" colloidal gold solutions. [2] [3] Notably, the formulation of Aurodye changed between ...
