Figure 2

FTIR of conjugated and unconjugated PAMAM dendrimer generation 3.0. The dashed line represents the unconjugated dendrimer. The dotted line represents the sialic acid conjugated dendrimer attached to dendrimeric termini via the carboxylic acid group. The solid line represents sialic acid conjugated dendrimer attached via the anomeric hydroxyl group of the sialic acid. The –COOH peak can be seen at 1730 cm−1 indicating linkage of sialic acid via the hydroxyl group and not the carboxylic acid group.
