title: TiO(2)-modified macroporous silica foams for advanced enrichment of multi-phosphorylated peptides.
abstract: Enriching peptides: Novel TiO(2)-modified macroporous materials (Ti-MOSF, see figure) have been synthesized with high surface area, large pore volume, and functional surfaces that are rich in coordinatively unsaturated Ti(IV) species, which can be applied in the specific extraction of phosphopeptides and which show a preferential capture of multi-phosphorylated peptides with low detection limits and high selectivity.
