摘要
Polyamidoamine dendrimers (PAMAM) form positively charged nanoparticles that function as nonviral delivery vectors for gene therapy. They protect nucleic acids from enzymatic degradation and facilitate endocytosis and endosomal escape. In this chapter, we describe the preparation and in vitro evaluation of small interfering RNA (siRNA)-PAMAM dendrimers. The physicochemical properties of the designed formulations were evaluated by size and zeta potential assessment and atomic force microscopy (AFM). The binding and release of the siRNA molecules from the PAMAM dendrimers were also assessed. Visualization and quantitative analysis of the siRNA-PAMAM dendrimers in live cells were analyzed by fluorescence microscopy and flow cytometry, respectively. Improving siRNA delivery to human cells through PAMAM dendrimers should accelerate the clinical applications of RNA interference.
