The development of new devices at the nanoscale level, as therapeutic support in medical practice, has facilitated the development of drug delivery systems (DDSs) based on nanoparticles. This enables the transport of an effective dose of therapeutic agents to target cells or tissues, with no collateral damage to healthy cells. Owing to their unique properties, nanoparticles doped with rare earths have demonstrated the potential of being used as a DDS of drug molecules to target cells or tissues. In the present work, ceria-doped titania nanoparticles (CeO2/TiO2NPs) were used to form the DNR-CeO2/TiO2NPs complex as a DDS of daunorubicin (DNR), which was tested in a B-lymphocyte cell culture. The CeO2/TiO2NPs were synthesized via the sol–gel process in a microemulsion of reverse micelle. In general, the results indicated that the nanoparticles presented good biocompatibility and load efficiency superior to that reported in other investigations for pure titania nanoparticles, suggesting that the CeO2/TiO2NPs increased intracellular accumulation of the drug. These results indicate that a delivery strategy using CeO2/TiO2NPs is a promising approach in the medical field, particularly in anticancer therapies.

AbstractThe covalent immobilization of crude lipases within silica-based macroporous frameworks have been performed by combining sol-gel process, concentrated direct emulsion, lyotropic mesophase and post-synthesis functionalizations. The as-synthesized open cell hybrid monoliths exhibit high macroscopic porosity, around 90 %, providing interconnected scaffold while reducing the diffusion low kinetic issue. The entrapment of enzymes in such foams deals with a high stability over esterification and transesterification batch process catalysis.

Nitrogen-doped titania nanoparticles were co-prepared by sol-gel and mechanical-alloying method. Raman spectroscopy was used to investigate the microstructure information of the nitrogen-doped titania nanoparticles. Besides, XPS, ESR and UV-vis absorption spectra were also analyzed as supplementary means. At first blue then red shift of 142 cm-1 peak was observed as the annealing temperatures increased. The possible reasons for the shift were discussed.
