My research explores the mechanisms governing the formation and degradation of mesoporous silica-based materials for drug delivery applications.

Uncovering the Dynamics of Mesoporous Silica Materials: From Formation to Degradation

The synthesis of mesoporous materials is a relatively straightforward process; however, the chemical and physical mechanisms that govern their formation are complex and not yet fully understood. A fundamental grasp of these processes is essential for optimizing material properties for specific applications. Additionally, the degradation of mesoporous materials significantly impacts their effectiveness for drug delivery. My research aims to provide a comprehensive understanding of the key parameters that influence both the formation and degradation of mesoporous silica materials. To achieve this, I employ advanced in-situ techniques such as synchrotron Small-Angle X-ray Scattering (SAXS) and Attenuated Total Reflection Fourier-Transform Infrared Spectroscopy (ATR-FTIR), along with molecular modeling, to investigate the structural dynamics involved in these processes.
