Gold Nanoparticles, Rhodamine B Labeled
Nanocs fluorescent labeled gold nanoparticles were made from monodispersed gold nanoparticles with narrow size distribution (<15%). Fluorescent molecules, from green to near infrared region, including fluorescein (FITC), rhodamine, Cy3, Cy5 or Alexa fluor dyes, were convalently attached to the gold surface. These fluorescently labeled gold nanoparticles are stable in aqueous buffer and is useful for generating various gold nanoparticle probes to detect various biomolecules in SEM, TEM, light microscopy and blotting.
