Abstract

The integration of a biosensor employing a DNAzyme logic system within a biofuel cell is presented. The self-powered DNAzyme logic biosensor conforms with INH logic operation and generates power output in accordance with a truth table. The new concept of logic-activated DNAzyme by the input signals has wide-ranging implications in the self-powered diagnostics domain.
