An omega-like DNA nanostructure utilized for small molecule introduction to stimulate formation of DNAzyme–aptamer conjugates.

An omega (Ω)-like DNA nanostructure was for the first time utilized for homogenous electrochemical monitoring of small molecules (ATP used in this case) based on target-induced formation of DNAzyme–aptamer conjugates without the need for sample separation and washing. [ABSTRACT FROM AUTHOR]
