Cytodiagnostics Methyl (methoxy) Gold Nanoparticles are made using a unique proprietary protocol resulting in particles with superior size distribution and shape compared to the leading competitor.

These non-protein binding methylated gold nanoparticles have a narrow size distribution (CV of less than 15%), prolonged shelf-life, reduced aggregation propensity and more than 95% spherical particles.

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.
