Abstract
A papertronic 64-well sensing array for rapid and sensitive screening of electroactive microorganisms was developed. This device offers a simple and facile approach to accurately characterize and simultaneously monitor bacterial electrogenicity without complicated fluidic feeding systems and electrical wires. After use, the entirely paper-based device platform can be disposed of safely by incineration without posing a risk of bacterial infection. Paper-based printed circuit boards integrated into the array effectively measured bioelectricity generated from spatially distinct 64 microbial fuel cells (MFCs) without cumbersome electrical connections. The flexible array performed stably through repeated folding cycles. Within 30 min, we successfully determined electrogenicity of 15 bacteria including two known wild-type electroactive microorganisms and thirteen isogenic mutants of P. aeruginosa. The paper-based MFC array could help transform electromicrobial technology from bench-top settings to practical applications that would demand proof of high performance.
