Advantages: Comprehensive characterization including TEM, UV-Vis, DLS Unique shape gold nanoparticles with spiky protrusion, which results in absorption of light in the far-red High purity, high monodispersity with narrow size distribution
Gold nanostars have unique optical properties compared to spherical gold nanoparticles of the same core diameter. The spiky uneven surface causes a red shift in the surface plasmon peak and a larger enhancement of the electromagnetic field at the tips of the gold nanostars spikes compared to that of spherical particles. Binding of ligands such as proteins to the gold nanostars surface also causes a larger shift in the surface plasmon resonance peak compared to standard spherical gold nanoparticles. This feature makes them ideal in the development of sensitive SPR-based detection assays.
