Encrypting messages with artificial bacterial receptors

Abstract
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.

Keywords: artificial receptors; cell surface modification; fluorescent
