NMR Relaxivity Properties Applications of Sol-Gel Procedures in MRI Contrast Agents 

Many of the proposed magnetic nanomaterials for the applications as contrast agents for MRI are coated by micro- and mesoporous silica obtained by standard sol-gel procedures. The essential nontoxicity of silica, the existence of simple functionalization procedures for surface silanol groups and their porosity, made this material the ideal choice for the production of multifunctional contrast agents (MRI and luminescent) with capability of drug delivery.
