abstract = {Conventional electronic circuits can perform multi-level
logic operations; however, this capability is rarely
realized by biological logic gates. In addition, the
question of how to close the gap between biomolecular
computation and silicon-based electrical circuitry is still
a key issue in the bioelectronics field. Here we explore a
novel split aptamer-based multi-level logic gate built from
INHIBIT and AND gates that performs a net XOR analysis, with
electrochemical signal as output. Based on the
aptamer–target interaction and a novel concept of
electrochemical rectification, a relayed charge transfer
occurs upon target binding between aptamer-linked redox
probes and solution-phase probes, which amplifies the sensor
signal and facilitates a straightforward and reliable
diagnosis. This work reveals a new route for the design of
bioelectronic logic circuits that can realize multi-level
logic operation, which has the potential to simplify an
otherwise complex diagnosis to a “yes” or “no”
decision.},
