Gold (Au) nanopowders have received considerable attention owing to their unique optical, electronic, and catalytic properties. The good conductivity and high melting point make them ideal candidates for the fabrication of electronic components such as transistors and memory devices. Recent studies have shown that with the small scale, Au Nanoparticles (AuNPs) can enter tissues and attack immune cells, like lymphoid tissues, rendering them potentially useful in immunotherapy. The attractive properties of Au nanopowders make them promising materials for wide range of applications such as sensory probes, therapeutic agents, emission management, drug delivery, catalysis, power cells, biological imaging, etc.
