A variety of neutral and cationic carbosilanedendrons containing a wide range of active groups, such as −N3, −OH, −NH2, and −SH, at the focal points were synthesized from carbosilane vinyl dendrons BrGnVm from generations 1–3 by substitution of the bromine atom at the focalpoint and functionalization of the vinyl groups via thiol-ene click chemistry with HS(CH2)2NMe2·HCl. These dendritic wedges were

surface of the nanoparticles. As nucleic acid model, a single‐stranded DNA oligonucleotide tagged with a fluorescent Cy3 moiety was used to evaluate the DNA adsorption capacity. The hybridmaterial functionalised with the third generation of a neutral dendron showed excellent DNA binding properties. Finally, the cytotoxicity as well as the capability to deliver DNA into cells, was tested in vitro by
