Beijing Biotyscience Co. Ltd provides high-quality spherical gold nanoparticles of different sizes. The aqueous solution of gold nanoparticles presents orange, red, purple and other colors depending on the particle size.

Gold nanoparticles have many applications in biology and medicine due to their unique optical and physical properties.

These versatile reagents can be used for biological immune detection, protein labeling, dark-field optical imaging, fluorescence enhancement, surface enhancement Raman substrate to meet the different experimental needs of scientific researchers.

By precisely engineering the gold nanoparticle surface, we also offer protein/antibody gold conjugates and particles with functional groups such as biotin, carboxyl, amine allowing them to be directly used in many applications.
