In photothermal cancer therapy, many gold nanoparticle molecules are used in each test and they must all be uniform in size. Including PEG coating, the nanoparticles measured to be ~130 nm in diameter. [1] Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm. [2]
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.
Gold nanoparticle filled and core-less spherical nucleic acid structures (SNAs). [ 1 ] Due to their structure and function, SNAs occupy a materials space distinct from DNA nanotechnology and DNA origami , [ 20 ] [ 21 ] (although both are important to the field of nucleic acid–guided programmable materials. [ 22 ]

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]
