Encapsulation and quantification of multiple dye guests in unmodified poly(amidoamine) dendrimers as a function of generation

This work illustrates the remarkable ability of amine-terminated PAMAM dendrimers to entrap multiple guest molecules. While previous encapsulation studies with dendritic polymers demonstrated multi-dye uptake, the dendrimers required extensive synthetic modification. This study utilizes unmodified PAMAM dendrimers to encapsulate multiple phenol blue molecules. Quantitative data on the uptake capacity and robustness of association is presented.
