The goal of the collaborative dendrimer project at Northern Kentucky University is to synthesize dendrimers capable of crossing the blood-brain barrier for drug delivery. This aspect of the research has focused on dual-functionalizing fourth and fifth-generation poly(amino)amide (PAMAM) dendrimers with the dansyl chloride fluorophore. The dual-functionalization will ultimately allow for dendrimers to have both fluorescent tags and moieties of interest (e.g., drugs) for future in vitro and in vivo studies.
