Gold Nanoparticles - Spherical Colloids
Gold nanoparticles are excellent for functionalization and use in a multitude of applications. We offer several options to give you a wide range of options to meet your scientific needs.
Our NanoXact Gold line is the foundation of our gold products. NanoXact particles are spherical, polycrystalline, and at concentrations of 0.05 mg/mL. When considering gold nanoparticles, most important is the quality of the colloid, but also is the cost. Our gold colloid is both high quality and at prices making a value that can't be matched.
For higher concentration options, we offer both BioPure Gold and PVP Gold that are both at 1 mg/mL. Example specification sheets are available on individual product pages.
