Description

Description générale

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.
