We are offering standard monodispersed spherical Gold Nanoparticles for biological and medical applications with different surface coatings, such as citrate, PVP, PEG, b-PEI, chitosan, beta-cyclodextrin, BSA and others.
For various applications, we can functionalize the surface of the nanoparticles with such substances as streptavidin, hyaluronic acid, collagen, cysteine, alginate, glutathione, proteins, and many others on your demand.
For cosmetic and cosmeceutical applications, various active ingredients and plants extracts can be used as surface coatings
We offer nanoparticles products with increased surface area: Nanoflowers and Nanostars. We can fine tune the ,,core diameter/branch length’’ ratio and UV-vis peak position according to customers’ requirements.
Various surface coatings are available and can be provided same as for Gold Nanospheres
We offer Gold Nanoparticles with modified surfaces, to create new properties or to provide a platform for further conjugation. We functionalize the NanoGold according to your demands to create positive or negative surface charge, to attach proteins, cyclodextrins, chitosans, streptavidin, etc. and to make the Nanoparticles stable in physiological liquids
