好的粒徑均一度 形態(tài) 穩定性，決定了好的蛋白吸附效果。

Our gold nanoparticle preparations have a narrow size distribution (CV of less than 12%), exceptional protein adsorption properties and more than 95% spherical particles. In addition, 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.



Storage



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



Do NOT freeze. Freezing causes irreversible aggregation of the gold nanoparticles.?



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