Abstract: A biocell having an electrochemical cell. The electrochemical cell includes an anode, a first cathode and a second cathode, and first and second porous separator membranes, wherein the first membrane is placed between a first contact surface of the anode and a first surface of the first cathode, and wherein the second membrane is placed between a second contact surface of the anode and a first surface of the second cathode.

Abstract: A device for producing and/or storing electrical energy (2), characterized in that the device comprises: an anode (4), a cathode (6), a separator (8) allowing for the transfer of at least one compound capable of triggering and/or enabling a production and/or storage of electrical energy (8), arranged between the anode (4) and the cathode (6), and at least one breakable, pierceable, and/or deformable reservoir (10) made of a compound capable of triggering and/or enabling a production and/or a storage of electrical energy, said reservoir (10) having means for bringing said compound and said separator (8) into contact with each other; said means for bringing said compound and said separator (8) into contact with each other being, in particular, means for transferring a liquid.

Abstract: Microfluidic devices fabricated from paper that has been covalently modified to increase its hydrophobicity, as well as methods of making and using thereof are provided herein. The devices are typically small, portable, flexible, and both easy and inexpensive to fabricate. Microfluidic devices contain a network of microfluidic components, including microfluidic channels, microfluidic chambers, microwells, or combinations thereof, designed to carry, store, mix, react, and/or analyze liquid samples. The microfluidic channels may be open channels, closed channels, or combinations thereof. The microfluidic devices may be used to detect and/or quantify an analyte, such as a small molecules, proteins, lipids polysaccharides, nucleic acids, prokaryotic cells, eukaryotic cells, particles, viruses, metal ions, and combinations thereof.
