Surfactants have a tendency to adsorb on the particle surface. Magnetic/Fluorescent surfactants can also adsorb on the particle surface and functionalize them to show a magnetic/fluorescence response. Some metals, such as Ho have inherent fluorescence. This property can be utilized for imparting a suitable surface with magnetic as well as fluorescent character. The effect of magnet on this property will be very interesting to check. In addition, the variation in the fluorescence in the premicellar, micellar and post micellar phases will be very interesting to observe and quantify.

Due to the porosity of the silica nanoparticles, It is expected that an enhanced magnetic response will be obtained from colloidal silica which will help to make these particles responsive to the magnetic field in an efficient way and consequently will make the particles available for different application based on magnetic responses such as memory devices, mobile screens etc.
