Significance of Gold nanoparticle
Gold nanoparticles (AuNPs) are nanoscale particles of gold ranging from 1 to 100 nanometers, known for their unique optical, physical, and chemical properties, which differentiate them from bulk gold. These particles have significant applications in various biomedical fields, including drug delivery, imaging technologies, vaccine development, and cancer treatment, due to their low toxicity and high stability. Their unique characteristics, such as strong light absorption and biocompatibility, make them essential in innovative medical therapies and diagnostics.
