A spatially-controlled DNA triangular prism nanomachine for AND-gated intracellular imaging of ATP in acidic microenvironment

A DNA triangular prism nanomachine (TPN)–based logic device for intracellular AND-gated imaging of adenosine triphosphate (ATP) has been constructed. By using i-motif sequences and ATP-binding aptamers as logic control units, the TPN logic device is qualified to respond to the acidic environment and...
