Reconfigurable Two-Dimensional DNA Molecular Arrays

Methods Mol Biol. 2023:2639:69-81. doi: 10.1007/978-1-0716-3028-0_4.

Abstract

In biology, molecular cascade signaling is an essential tool to mediate various pathways and downstream behaviors. Mimicking these molecular cascades plays an important role in synthetic biology. The use of DNA self-assembly represents an elegant way to build sophisticated molecular cascades. For instance, a DNA molecular array connected by a number of dynamic anti-junction units was able to realize prescribed, multistep, long-range cascaded transformation. The dynamic DNA molecular array is able to execute transformations with programmable initiation, propagation, and regulation. The transformation of the array can be initiated at selected units and then propagated, without addition of extra triggers, to neighboring units and eventually the entire array.

Keywords: Cascaded transformation; DNA nanostructure; Reconfigurable 2D arrays; Self-assembly.
