Abstract

In recent years, use of SOL-GEL procedure for laboratory and industrial synthesis of Nanostructures and especially SILICA Nano-particles has increased. In this research, SILICA particles were synthesized by SOL-GEL procedure and their physical properties were studied by means of Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Thermal Gravimetric Analysis (TGA). Effect of structural MODIFIERs on the MORPHOLOGY and diameter of Nano-particles was investigated. In addition, the reaction was carried out in the presence of ULTRASONIC WAVES in periods of 10, 30 and 60 minutes and the effect of these waves on different stages of reaction was studied by means of SEM. Finally, in this research, spherical particles of 50 to 80 nanometer sizes were synthesized and characterized. They can be very useful hosts for lanthanide complexes that can be used in drug delivery systems, radiotherapy, photoluminescence applications and manufacturing of special lasers. Also, different amounts of Lanthanum Nitrate hexahydrate were added to the mixture during the creation of Nano-particles. Then, Simulated Body Fluid (SBF) was produced for the study of ability of the Nanostructures in regulated delivery of drugs such as Lanthanides, and releasing of Lanthanides in 10 minute periods for 80 h was studied. Lanthanide concentration in SBF was also studied by means of Inductively Coupled Plasma (ICP). According to the results of ICP, loaded Lanthanide was not released from the SILICA network. Loaded Lanthanides in the mesopores can be used in radiation, especially in cases of liver cancer.
