Product Overview<\/b><\/strong><\/h3>\n

Gold nanostars are gold nanoparticles with multiple sharp tips, which result in significant electric field enhancement at the sharp tips. These nanostars are synthesized using a chlorogold acid reduction method and surface-modified with HEPES. Due to their unique structure, gold nanostars exhibit exceptional performance in surface plasmon resonance (SPR) enhanced spectroscopy, particularly with strong optical absorption in the near-infrared region. This makes them highly suitable for applications in optical imaging, photothermal therapy, and biosensing.<\/p>\n
