| Research Abstract |
Mass transfer processes of a solute(s) in a porous microparticle/solution system hasbeen analyzed using a confocal fluorescence microspectroscopy and absorptionmicrospectroscopy combined with single microparticle manipulation method. Timedependence of the concentration profile of a fluorescent dye adsorbed in a singlemicroparticle such as silica gel and octadecylsilyl (ODS)-silica gel possessing mesoporeswas directly measured by the technique. Surface/pore diffusion and migration of the dyein the mesopores and uptake/release of the dye at the pores of the micropartice surfacewere discussed in terms of the pore/solute size, ionic strength in the solution, and soforth.
