Four sizes of standard non-functionalized Gold NanoUrchins combined in a convenient kit for testing optimal size, suitability and stability during your protocol development.


Our Gold NanoUrchins are unique spherical gold nanoparticles with spiky protrusions, which leads to absorption of light in the far-red.

Our Gold NanoUrchins have a narrow size distribution (CV of less than 8%) and exceptional protein adsorption properties. Low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered.

All of our batches go through stringent quality control prior to shipment to our customers to guarantee size and monodispersity. Lot specifications are included with every shipment.


Store product away from direct sunlight at 4-25°C. Lower temperature prolongs the shelf life of the product.

Do NOT freeze.

When stored as specified the product is stable for at least six months.
