<p>Encrypting messages with artificial bacterial receptors</p>
<p>Abstract<br>
A method for encrypting messages using engineered bacteria and
different fluorescently labeled synthetic receptors is described.
We show that the binding of DNA-based artificial receptors to E.
coli expressing His-tagged outer membrane protein C (His-OmpC)
induces a Förster resonance energy transfer (FRET) between the
dyes, which results in the generation of a unique fluorescence
fingerprint. Because the bacteria continuously divide, the
emission pattern generated by the modified bacteria dynamically
changes, enabling the system to produce encryption keys that
change with time. Thus, this development indicates the potential
contribution of live-cell-based encryption systems to the emerging
area of information protection at the molecular level.<br>
