2. Gold nanoparticles in chemotherapy - Wikipedia

   en.wikipedia.org/wiki/Gold_nanoparticles_in...

   Gold nanoparticles. 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 ...

3. Colloidal gold - Wikipedia

   en.wikipedia.org/wiki/Colloidal_gold

   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 ]

4. Polyvalent DNA gold nanoparticles - Wikipedia

   en.wikipedia.org/wiki/Polyvalent_DNA_gold...

   Gold nanoparticles can be purchased or synthesized via a variety of methods. [12] Several strategies exist for functionalizing gold nanoparticles with single-stranded DNA; one of the most commonly utilized strategies involves introducing thiol-terminated DNA to a solution of gold nanoparticles and gradually increasing the concentration of a salt, like NaCl.

5. Chloroauric acid - Wikipedia

   en.wikipedia.org/wiki/Chloroauric_acid

   Reduction may also yield other gold(I) complexes, especially with organic ligands. Often the ligand serves as reducing agent as illustrated with thiourea, CS(NH 2) 2: [AuCl 4] − + 3 CS(NH 2) 2 + H 2 O → [Au(CS(NH 2) 2) 2] + + CO(NH 2) 2 + S + 2 Cl − + 2 HCl. Chloroauric acid is the precursor to gold nanoparticles by precipitation onto ...

6. Immunogold labelling - Wikipedia

   en.wikipedia.org/wiki/Immunogold_labelling

   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 ...

7. Gold nanocage - Wikipedia

   en.wikipedia.org/wiki/Gold_nanocage

   Gold nanocage. Gold Nanocages are hollow, porous gold nanoparticles ranging in size from 10 to over 150 nm. They are created by reacting silver nanoparticles with chloroauric acid (H Au Cl 4) in boiling water. [1] Whereas gold nanoparticles absorb light in the visible spectrum of light (at about 550 nm), gold nanocages absorb light in the near ...
