Gold nanostars Creative Diagnostics offers a comprehensive list of functional and conjugated Nanostars. We provide Nanostars functionalized with active groups such as NHS, carboxyl, amine and hydroxyl. Conjugated nanostars with a variety of biological ligands are available for your unique requirements. 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. 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
