Molecule-Surface Dynamics in Functionalized Mesoporous Silicon
Abstract
The primary goal of this project is to gain understanding of the impact of porous silicon functionalization chemistry and morphology on the surface interaction mechanisms involved in macroscopic diffusion and attachment of different chemical and biomolecular species in porous silicon films and membranes. In particular, we will seek to increase the state of knowledge in the following areas: 1) Effect of surface passivation layer (e.g., oxide, carbon, metal) on molecular and ionic diffusion through porous silicon films; 2) Effect of pore morphology, including closed-ended and open-ended pores, on diffusion rates; and 3) Diffusion and attachment dynamics and efficacy of molecular capture in porous silicon films functionalized for specific binding (e.g., DNA, peptide, antibody bioreceptors).
