Gold nanoparticles are known for their unique properties, and in particular for photothermal and optical properties related to Surface Plasmon Resonance (SPR), a phenomenon involving the collective oscillation of conducting electrons, which confers them their characteristic bright-red color.
Thanks to their characteristic plasmonic properties and versatile surface functionalization capabilities they are used in countless applications, like in the fields of molecular diagnostics and (bio)sensing, imaging, photothermal therapy etc.
RHP Gold Nanoparticles are characterized by extremely long-term colloidal stability and high purity, which makes them especially suitable for applications in the field of life sciences and catalysis, and where the absence of any chemical residuals is critical.
Thanks to their high surface area and surface chemistry, RHP gold nanoparticles can be easily functionalized. The particles are spherical in shape (>99%) with no sharp edges, allowing uniform access to molecules binding sites and fast conjugation.
RHP Gold Nano-Colloids are available in various liquid carriers and in a large concentration range. Please download our catalogue for more information.
