Gold nanoparticles (AuNPs) are tiny particles of gold that range in size from 1 to 100 nanometers and exhibit unique optical, electronic, and chemical properties compared to bulk gold. Their small size and large surface area make them highly reactive and suitable for a wide range of applications, especially in medicine and diagnostics. One of their most notable characteristics is surface plasmon resonance (SPR), which gives them the ability to absorb and scatter light efficiently. This property makes gold nanoparticles ideal for use in imaging techniques, biosensing, and photothermal therapy.
In biomedical fields, gold nanoparticles are widely used for targeted drug delivery, cancer treatment, and as contrast agents in imaging. Their biocompatibility and ability to be easily functionalized with various biomolecules enhance their effectiveness in targeting specific cells or tissues. Additionally, they are employed in environmental monitoring, electronics, and catalysis. Ongoing research continues to expand the potential of gold nanoparticles, particularly in developing more precise and non-invasive diagnostic tools and therapies, making them a valuable component in nanotechnology and modern medicine.
