Abstract
Methods of synthesizing gold nanodendrites (AuNDs) using amines, such as long chain amines, as a structural directing agent are disclosed. Degree of branching (DB) of the AuNDs can be tuned by adjusting certain synthetic parameters, such as solvent type, and the type and concentration of the long chain amines. DB control results in dramatic tunability of the optical properties of the AuNDs in the near infrared (NIR) range enabling improved performance, for example as a photothermal cancer therapeutic.
Claims20
A method of forming gold dendritic nanoparticles, comprising:
- providing a quantity of seed nanoparticles comprising elemental gold;
- providing an amine-solvent solution comprising at least one long chain primary amine disposed in a solvent;
- providing an ionic gold solution;
- providing a reducing reagent solution;
- combining the quantity of seed nanoparticles, the amine-solvent solution, the ionic gold solution, and the reducing reagent solution in a container to form a mixture, and agitating the mixture for a duration of time sufficient to cause formation of dendritic gold nanoparticles in the mixture;
- and
- isolating the dendritic gold nanoparticles from the mixture.
