In recent years, it has been used in fields related to diagnostics, pharmaceuticals, biomarkers, markers for X-ray analysis, and other applications in high-tech ares like organic solar cells and catalysts.
We measured the particle diameter and electrical mobility of commercially available colloidal gold charaxterized by different particle diameters.
