The lectin-binding properties of six generations of mannose-functionalized dendrimers.

[structure: see text] First- through sixth-generation PAMAM dendrimers have been functionalized with mannose residues. Characterization with MALDI-TOF MS and (1)H NMR is reported. Different binding enhancements consistent with monovalent interaction, glycoside clustering, and multivalent binding are observed for different generations of dendrimers.
