We demonstrate an electrically conductive paper-based screening platform for the high-throughput and rapid characterization of the electricity-producing capability of microorganisms. This novel screening sensor substantially improved the device fabrication, sensitivity, reliability, and scalability by simply patterning hydrophilic reservoirs in paper with hydrophobic wax boundaries and adding water-dispersed...
In this work, we report paper-based microbial fuel cells (MFCs) that produce high power and current densities from one drop of bacteria-containing liquid. The devices feature (i) a simple and versatile fabrication technique by using paper as a substrate and (ii) an exceptional performance by incorporating novel nanostructured polymers, PAA-Poly (amic) acid) and PPDD-Poly(pyromellitic dianhydride-p-phenylene...
In this work, we provided a strategy for high-throughput monitoring of temporal and spatial gradients of electrons/protons in electrogenic bacterial biofilms by utilizing 3D multi-laminate structures of paper as a scaffold to support bacterial biofilms and/or media. Assembly of a 3D paper stack can be modular and allows us to control the thickness of the overall biofilm construct and diffusion of...
In this work, we provided a new technique to monitor the flow of bacterial cells in paper. This was based on real-time measuring of the electricity generated from bacterial metabolism. Despite recent efforts to monitor liquid flow in paper, there is not yet a technique that provides detailed flow information of particles in paper microfluidics. Our device contained three hydrophilic spots linked by...
In this work, we created a stackable, 3-D, paper-based, bacteria-powered battery for potentially powering on-chip paper-based biosensors. The battery generated power from microbial respiration with one drop of bacteria-containing liquid. An air-cathode was also created on paper with activated carbon on the Nickel electrode that was sprayed on the paper. By applying paper-folding techniques, the four...
We report an array of three microliter-sized microbial fuel cells (MFC) that can produce 100 μW. Individual MFCs were integrated on two sandwiched glass slides, and had two 50 μL-sized chambers each (Geobactor sp. in the anode, ferricyanide in the cathode chambers, respectively) separated by a cation exchange membrane (CEM). The three MFCs were formed in a series array to produce 1.8 V at the maximum...
