The golden age: gold nanoparticles for biomedicine

On the application potential of gold nanoparticles in nanoelectronics and biomedicine.

Ligand-stabilized gold nanoparticles (AuNPs) are of high interest to research dedicated to future technologies such as nanoelectronics or biomedical applications. This research interest arises from the unique size-dependent properties such as surface plasmon resonance or Coulomb charging effects. It is shown here how the unique properties of individual AuNPs and AuNP assemblies can be used to c...

The golden pathway to thiolate-stabilized nanoparticles: following the formation of gold(I) thiolate from gold(III) chloride.

Pathways for the formation of gold thiolate complexes from gold(III) chloride precursors AuCl(4)(-) and AuCl(3) are examined. This work demonstrates that two distinct reaction pathways are possible; which pathway is accessible in a given reaction may depend on factors such as the residue group R on the incoming thiol. Density functional theory calculations using the BP86 functional and a polari...

Applications of gold nanoparticles for medical imaging

Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
