In the realm of modern science and technology, gold has transcended its traditional role as a symbol of wealth and luxury. Today, it is the subject of cutting-edge research in laboratories across the globe β not in the form of bars or jewelry, but as gold nanoparticles. These tiny particles, measured in billionths of a meter, are transforming how we approach problems in medicine, electronics, environmental science, and materials engineering.
What Are Gold Nanoparticles?
Gold nanoparticles (AuNPs) are minute particles of gold that typically range between 1 and 100 nanometers in size. At this scale, gold behaves very differently from its bulk form. It exhibits unique optical, electronic, and chemical properties, making it incredibly valuable for scientific research. These properties are not just intriguing; they are powerful tools in developing new technologies and improving existing ones.
