Abstract: The invention relates to an apparatus for purifying fluids comprising at least one electrochemical cell having a cathode (3), an anode (5) and an electrolyte (7), said cathode (3) comprising a metal complex, ML, where M represents a metal and L represents an organic or inorganic ligand, said complex being capable of forming the hydroxyl radical by a reaction wherein the metal in the complex is oxidised and acquires an additional positive charge, said anode (5) creating positive ions and electrons, said electrolyte (7) allowing the transfer of a positive charges, said cathode being arranged such that the fluid to be purified can come into contact with the metal complex on the cathode. The invention also provides a related electrode and a related electrochemical cell as well as a corresponding method for purifying fluids.

Abstract: The invention relates to a chemical sensor comprising a sensor film formed of a nanoparticle network in which the nanoparticles are interlinked by functionalized dendrimer molecules. The dendrimers support an efficient uptake of analyte molecules by the film material and therefore enable a high sensitivity of the sensor. In addition, the chemical nature of the dendrimers strongly determines the chemical selectivity of the sensor device. By cross-linking the components of the sensitive material the sensor displays a good mechanical stability.

Abstract: Disclosed is an electronic device comprising a nanoparticle structure and configured such that, when driven by a power source, a current path is defined through said nanoparticle structure, wherein the nanoparticle structure comprises a substrate and metal and/or semiconductor nanoparticles, wherein the nanoparticles are linked to each other and/or to the substrate by bifunctional or polyfunctional ligands. The invention especially relates to an electronic device in the form of a sensor for detecting one or more analytes in a liquid or a gas phase.

Abstract: The invention relates to a nanoparticle film comprising a nanoparticle network formed of nanoparticles interlinked by linker molecules. The linker molecules have at least two linker units that can bind to the surface of the nanoparticles. By introducing selectivity-enhancing units in the linker molecule, the selectivity of the nanoparticle film towards target analytes can be enhanced. A fine-tuning of the selectivity can be achieved by including a fine-tuning unit in the vicinity of the selectivity-enhancing unit. The nanoparticle film can be used to produce chemical sensors which are selective and stable in their performance.
