Abstract
Given the growing importance of drug and gene delivery systems, imaging agents, biosensors, and theranostics, there is a need to develop new multifunctional and biocompatible platforms. Here we synthesized and fully characterized a family of novel multifunctional and completely monodisperse dendritic platforms. Our synthetic methodology, based on compatible protecting groups and the attachment of monodisperse triethylene glycol units, allows the control of the generation and differentiation of terminal groups, thus giving rise to multifunctional and perfectly-defined products. A family of dendrons was synthesized and four distinct dendritic structures were chosen from the family in order to determine the effect of the generation and surface groups on their biocompatibility. The stability in serum, cytotoxicity, and hemocompatibility of these products were studied. Our results indicate that these non-toxic, hemocompatible, non-immunogenic, stable and versatile scaffolds may be very interesting candidates for biomedical applications.
