Gold nanoparticles (AuNPs) are tiny gold particles of 1–100 nanometers and have unique chemical and biological properties. Due to their potential to accumulate in tumors, these nanoparticles have ...

While the gold particles may appear microscopic, the net quantity can make up about 80 grams of the valuable element, estimated to be worth $6000, per a study published in the journal Advancing ...

Background: Positive patch-test reactions to gold that are without obvious clinical relevance are common. We speculate that titanium dioxide in cosmetics and sunscreens may adsorb gold particles ...
