Gold nanoparticles (AuNPs) are nanoscale particles of gold, typically ranging in size from 1 to 100 nanometers (nm). These nanoparticles exhibit unique physical, chemical, and optical properties that ...

Gold has been known since prehistoric times. It is a soft metal with a characteristic yellow colour. Gold is the most malleable and ductile of any element. It is unaffected by air, water, alkalis and ...

Gold nanorods are promising photocatalysts that can use light energy to drive chemical reactions—such as converting CO₂ into ...
