Descrição geral

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

Aplicação

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.
