Abstract: The invention concerns a chemical compound comprising a chemical moiety (p) capable of performing a binding interaction with a target molecule (e.g. a biological target) and further comprising an oligonucleotide (b) or functional analogue thereof. In a first embodiment according to the invention, the chemical compound is characterized in that the oligonucleotide (b) or functional analogue comprises at least one self-assembly sequence (b1) capable of performing a combination reaction with at least one self-assembly sequence (b1?) of a complementary oligonucleotide or functional analogue bound to another chemical compound comprising a chemical moiety (q).
