We present a novel optical fiber dynamic light scattering measurement system for nanometer particle size. A multimode fiber probe is used to highly efficiently couple and deliver laser light, while a single-mode fiber probe is used to only receive single scattering light. This design not only improves the measuring ability of the system but also provides flexibility in choosing scattering angle for measurement. By using this system, four kinds of polystyrene nanoparticles are evaluated. Experimentation shows the measured sizes of the nanoparticles are well consistent with the nominal ones, verifying the feasibility of the system.

The adsorption process on aqueous phase can be described as the exchange between a solvent molecule eletrostatically attracted to a solid surface and the molecule of a given solute. In this research the capability of three different silica materials in removing a dye from water was evaluated using an optical fiber sensor. Despite the better results, the nanomaterials data showed higher dispersion due to the presence of dynamic light scattering on particles which got stably suspended, and crystalline quartz showed the lowest manufacturing cost.
