Application

Gold nanoparticles can be used:

As a catalyst in the preparation of single-walled carbon nanotubes by a chemical vapor deposition method.
In the preparation of conducting polymer matrix AuNPs/PEDOT: PSS(poly(3,4-ethylenedioxythiophene) polystyrene sulfonate), which is applicable in fuel cell electrocatalysis.
To prepare fluorescent nanocomposites for targeted bioimaging.
As carriers of signaling antibody in developing optical ELISA for analysis of breast cancer biomarker.

General description

Gold nanoparticles are extensively used as preferred materials for labeling, imaging, sensing, and biomedical applications due to their following unique properties:

Ease of synthetic manipulation
Strong binding affinity to thiols, disulfides, and amines
Unique tunable optical and distinct electronic properties
High X-ray absorption coefficient
