Definitions

  • the invention relates to a bioelectrical arrangement in which at least one biological component is used, the use of the arrangement as a radiation sensor for detecting different types and intensities of radiation, for detecting those compounds which contain the enclosed biological material influence its sensitivity to radiation, and enables it as a solar battery.
  • a bioelectrical arrangement is known in which a photosensitive protein is enclosed in an oriented manner in a membrane and applied to a substrate. To stabilize the oriented molecules, it is covered with a polymer film (Japanese patent application 241 432/1988). Furthermore, an arrangement is known in which the oriented membrane molecules by adding certain substances and using certain methods, such as. B. the electrophoresis, can be crosslinked (EP 0 417 541). In this case, the membranes, which can consist of one or more protein layers, are stable without a special covering.
  • Another disadvantage is that the biological material used in the arrangements must be in a highly purified form.
  • the invention is based on the object of simplifying the process of orienting and stabilizing radiation-sensitive biological material in bioelectrical arrangements, avoiding the use of extremely highly purified biological material and converting radiation energy by biological material in the simplest form into electrical energy.
  • this object is achieved by the technical teachings of claim 1.
  • radiation-sensitive biological material such as rhodopsin
  • embedded in a lyotropic liquid crystal is used as the material for the bioelectrical arrangement.
  • these liquid-crystalline arrangements have not been used to convert radiation energy into electrical energy.
  • electrodes can be arranged directly on the liquid.
  • intermediate layers had to be provided in order to be able to tap the electrical signals.
  • a dye When using the arrangement as a radiation sensor, a dye can be embedded in the liquid crystal, which changes its color due to an electrochemical reaction. In this way, a radiation sensor is created in the simplest way. Phenolphthalein can be used.
  • Microorganisms which contain at least one radiation-sensitive substance can also be used very advantageously as radiation-sensitive biological material.
  • algae from the Chlorella-kessleri strain can be used.
  • cells it is possible to use cells as radiation-sensitive biological material which contain at least one radiation-sensitive substance.
  • the radiation-electrical effect occurs without external orientation of the radiation-sensitive molecules.
  • the arrangement according to the invention can emit a higher measuring voltage at the same concentration of the radiation-sensitive molecules, so that the simplest measuring systems can be used.
  • a standard recorder can be connected to the sensor.

Abstract

Dans un agencement bioélectrique, on utilise un matériau biologique photosensible, tel que la rhodopsine. Le matériau biologique est pris dans un cristal liquide lyotrope, ce qui permet d'obtenir l'effet photoélectrique sans qu'il soit nécessaire de prendre des mesures particulières depuis l'extérieur. Un autre avantage offert par cet agencement est l'élimination de l'épuration poussée du matériau biologique utilisé.
