Particle agglomeration and sedimentation in the absence of serum. DLS determinations of the average particle size of nano-Silicon Dioxide dispersed in culture medium without addition of serum were distinctly different from those obtained in the presence of serum. Incubations were performed under similar conditions. except that serum was omitted from the culture medium. The results show variation in the z-average, which is indicative of particle agglomeration, and a marked decrease in the count rate indicative of a loss of particles from the suspension and consistent with particle sedimentation.

Nano-Silicon Dioxide plays an important role in technology. With the development of science and technology and human living standards improved, people have requirements on clothing comfort, innovative, health requirements, a variety of functional clothes appeard. Nowadays, people have applied to nano-Silicon Dioxide to anti - ultraviolet, far infrared, antibacterial deodorant, anti-aging, etc. Nano-SiO2 and TiO2 Nanoparticles at appropriate ratio to make composite powder is an important additive UV resistant fiber.
