ABSTRACT
In this work, highly reversible end-to-end assembly of gold nanorods (AuNRs) has been achieved based on pH-responsive DNA nanomachine. In this system, the polyvalent linkages between AuNRs and duple cyclic disulfide group-modified DNA molecules tremendously enhanced the stability of the AuNRs-DNA conjugates. The excellent controllability and reproducibility of the assembly was demonstrated through consecutive assembly/disassembly cycles. This strategy is expected to be used for precise construction and manipulation of more complex functional nanodevices.

    Motivation: Biologists usually work with textual DNA sequences (succession of A, C, G and T). This representation allows biologists to study the syntax and other linguistic properties of DNA sequences. Nevertheless, such a linear coding offers only a local and a one-dimensional vision of the...
