Abstract

Here, we describe the design and synthesis of a new reduction-cleavable spacer (RCS) based on a nitrobenzene scaffold for constructing reduction-responsive oligonucleotides according to standard phosphoramidite chemistry. In addition, we demonstrate that the introduction of the RCS in the middle of an oligonucleotide (30 nt) enables the construction of a self-assembled microsphere capable of exhibiting a reduction-responsive disassembly.

Keywords: DNA structures; cleavage reaction; reduction; self-assembly.
