Abstract

Drug delivery systems are increasingly studied or even used for a wide range of biomedical applications [1-3]. Internal or external factors can be used to tune the delivery of the biologically active agents and thus to assure the optimal conditions. Micro and Mesoporous materials are widely used as drug delivery system because they can assure the desired controlled release of a wide range of biologically active agents. Usually, mesoporous silica exhibit large surface area and good surface reactivity to be easily functionalized and thus to assure the desired delivery profile considering especially surface modification, pores' characteristics, and triggering factors. Starting from the advantages of the mesoporous silica supports, innovative drug delivery systems can be developed in order to obtain targeted drug delivery systems. In this work, several examples of drug delivery systems based on mesoporous silica and different polyphenols will be discussed.
