      Abstract: Strategies were developed by which   mesoporous microparticles were modified on their external   surfaces with tetraethylene glycol (TEG), a protein, or both,   leaving the pore surfaces available for modification with a   separate moiety, such as a dye. Only particles bifunctionally   modified with both TEG and a cell-specific antibody were taken up   specifically by a targeted cancer cell line. In contrast to   similarly functionalized nanoparticles, endocytosed   microparticles were not contained within a lysosome.
