For the quality assurance of nanoparticles, nanoparticles size evaluation tool is required. In this study, nanoparticles size evaluation method based on fluorescence polarization is proposed. We also developped the method to control the nanoparticle aggregation by using deveolopped nanoparticle sizing system. Fundamental investigation using the nano particle sizing system is performed for 10 nm gold nano particle Gold nanopartilce and standard particle is measured with varying viscosity and temperature, and the measurement results are relatively agree with the change of the nanoparticle sizes.
