Streptavidin - 70nm Gold NanoUrchins Lyophilization:No Lyophilization (M-1cm-1) Size Dispersity (+/-nm) Particle

(M-1cm-1) Size Dispersity (+/-nm) Particle Volume (nm3) Surface Area (nm2) Surface/Volume Ratio Particle Mass (g) Molar Mass (g/mol) Molar Concentration* 80 620 7

Core diameter: 80nm

Absorption max: 425-440nm

This generally results in poor performing conjugates in downstream applications and could also impact the stability of the conjugate

Silver nanoparticles are a great alternative to gold nanoparticles if absorption maximum is desired in between 400-500nm
