“There are an enormous number of people using gold nanoparticles,” says Chad Mirkin, a chemist at Northwestern University whose own studies focus on how the particles could help turn off genes ...

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 ...

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 ...

Indeed, positive gold ions can react with noble gases, and gold particles just a few nanometres in diameter can act as catalysts in many reactions, as can single gold atoms bound in suitable ...

Unless market conditions dramatically change, geopolitical tensions significantly cool or stock market performance starts consistently improving, gold's price is likely to reflect these concerns ...

The paper is published in the journal Nature Electronics. By incorporating gold nanoparticles within the electrode, the team significantly reduced its resistance, leading to a substantial ...
