“…Most nonviral nucleid acid carriers (vectors) reported are polymeric, conformationally undefined or complex nanoparticulate materials [ 85 ]. In the last decade, however, multivalent polycations based on molecular systems emerged as a promising alternative [ 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 ]. Polycationic cyclodextrins have become the iconic representatives in this category [ 5 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 ].…”
