Silver Nanospheres (Nanoparticles) are of highest quality and can be used in production of diagnostic tests as well as conjugation studies of proteins and antibodies. The particles have a narrow size distribution ( CV between 10% and 20% depending on size ) and are available from 2nm to 250 nm. They are supplied in 100 ml solution at optical density of 1.0, measured at 520 nm. The number of particles/ml is given in the product/ordering table. Prices of bigger quantities on request.
