Gold NanoUrchins (GU)
Non-functionalized Gold NanoUrchins 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 electromagnetic fields at the tips of the Gold NanoUrchin spikes compared to that of a spherical particles. As an example, 100nm spherical gold nanoparticles have an SPR peak at 570nm while 100nm Gold NanoUrchins have a SPR peak at around 680nm. In addition, binding of ligands such as proteins to the Gold NanoUrchin surface causes a larger shift in the surface plasmon peak compared to standard spherical gold nanoparticles.

The citrate-covered surface of the Gold NanoUrchins allows for efficient adsorption of primary antibodies and other proteins. Also, Gold NanoUrchins can be further modified and functionalized through ligand-exchange with e.g. thiol-containing ligands such as PEG and oligonucleotides. These particles can be used as an alternative to standard spherical gold nanoparticles in a wide range of applications such as electron microscopy, immunostaining and development of biological sensors.
