  • Sensor for measuring the activity of beta-pancreatic cells or of islets of langerhans, manufacture and use of such a sensor
    Patent number: 9962113
    Abstract: The invention relates to a sensor (2) including: a microelectrode assembly (21); and ?-pancreatic cells (23) or islets (230) of Langerhans in culture on the microelectrode assembly (21); characterized in that the microelectrode assembly (21) is designed to measure dynamically, continuously and in real time, electrical signals (V) produced by the ?-pancreatic cells (23) or the islets of Langerhans (230) upon physiological activation. The invention also relates to the field of devices that can be implantable in the body of a patient, and including an insulin dispenser for dispensing an amount of insulin. The invention also relates to a method for manufacturing such a sensor and to such a device and a use of such a sensor.

  • Oxidase process for pulp
    Patent number: 6660128
    Abstract: A method for selectively delignifying lignocellulosic materials and bleaching of pulp and dyes using a combination of an oxidative enzyme and a metal complex. More specifically, the process involves the oxidation of a transition metal redox complex by a phenol oxidizing enzyme such as laccase or peroxidase to mediate the catalytic delignification of chemical pulp and bleaching of textile dye. This process is unique in that only a catalytic amount of metal complex mediator is required on softwood or hardwood kraft pulp, and that recycling or regeneration of the mediator for further pulp delignification is possible. The redox mediator is characterized in that it contains a transition metal ion coordinated with molecules or ions in such a way that the complexes have a formal redox potential between 0.5 and 1.2 volt measured against a normal hydrogen electrode.
