These non-protein binding methylated gold nanourchins have a narrow size distribution (CV of less than 10%), prolonged shelf-life and reduced aggregation propensity due to the protective PEG-layer.

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 using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.


Store product away from direct sunlight at 4°C. Do NOT freeze. When stored as specified the product is stable for at least twelve months.
