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
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.
