New Insights into Behaviour of Gold Nanoparticles
In September 2025, scientists uncovered how gold nanoparticles—the tiny particles that give rise to powerful optical technologies—change their behaviour when exposed to everyday molecules like amino acids and salts.
- This breakthrough paves the way for smarter biosensors, better diagnostic tools, and more reliable drug delivery systems.
What are gold nanoparticles?
- Gold nanoparticles (AuNPs) are extremely small particles of gold, typically ranging from 1 to 100 nanometers, where one nanometer is one-billionth of a meter.
- At this scale, gold exhibits unique optical, chemical, and biological properties that differ from bulk gold.
- Gold nanoparticles are highly sensitive to their environment, which is why controlling ....
