Definitions

  • the present invention relates generally to a method and an apparatus for optophysical detection of analytes.
  • the invention relates to the miniaturization of previously known systems in which an analyte is detected by color recognition directly on the chip to which the analyte is applied.
  • Biomolecules in a sample to be analyzed the use of essentially planar systems is known, which are referred to in the art as biosensors or biochips. These biochips form a carrier, on the surface of which, as a rule. a multiplicity of detection areas, most of which are arranged in a grid, is formed, the individual areas or area groups each differing from one another in their specificity with respect to a specific analyte to be detected.
  • specific nucleic acid probes such as, for example, are located within the individual regions of the carrier surface - directly or indirectly immobilized.
  • oligonucleotides or cDNA in mostly single-stranded form, the specificity of which relative to the nucleic acid to be detected is essentially determined by the sequence sequence (probe design).
  • biosensors or biochips are known, for example, from WO 03/008974 AI, in which the detection of analytes is described by means of time-resolved luminance measurements.
  • test strips for the detection of analytes are known to experts. With these test strips, their color changes within z. B. 60 seconds depending on the composition of the analytes. In principle, this color change is based on the fact that e.g. For example, a blue object absorbs the wavelengths complementary to blue and only reflects or transmits the blue wavelengths. The reason for this is that the electrons of the substance can only be brought into an excited state by certain wavelengths. Now something changes in this substance, e.g. If, for example, an analyte with a specific pH value is applied, other wavelengths are absorbed, which means that the object has a different color. In the test strips are z. B. important components such. B.
  • methyl red and bromothymol blue which can change depending on the pH range between 5 and 9 from orange to yellow to turquoise. This color change can then be recognized by the eye under normal lighting conditions and assigned to a color scale supplied by the manufacturer, which is not always easy. So z. B. Test strips for the detection of urobilinogen, bilirubin, ketone, ascorbic acid, glucose, protein, blood, pH, nitrite, leukocytes and specific weight. Despite the high reliability of the test strips, e.g. B. Urines with strong intrinsic color deceive the human eye in the rapid test evaluation. The use of the human eye limits the wavelengths. Different lighting conditions can also play a role.
  • the currently known methods for reading the test strips are larger devices and the method separates the detection from the reaction of the analyte, since the test strip is pushed into the test device for reading after the reaction.
  • the method separates the detection from the reaction of the analyte, since the test strip is pushed into the test device for reading after the reaction.
  • usually only one component of the analyte per test strip can be read.
  • test strip or the reactive layer is integrated in the test device, so that the reaction of the analyte and the detection of the reaction do not take place separately in the above sense.
  • the reactive layer is arranged directly on a detector for detecting the reaction.
  • only one component of the analyte can be detected here per reactive layer or per test strip.
  • the object is therefore to create a device of the type mentioned at the outset which, while avoiding the disadvantages mentioned above, enables a high parallel measurement of several constituents of an analyte in a simple and compact structure.
  • the camera chip is a CMOS or CCD chip, as is known to the person skilled in the art from the prior art.
  • a pixel of such a color camera basically consists of three sub-pixels, each of which is sensitive to the colors red, green and blue.
  • On this camera chip different chemical substances are directly or indirectly via z.
  • not only one but at least two substances for analyzing two different components of the analyte are applied to an area of the camera. This can be done either as a stack or as a mixture. Because the absorptions of the wavelengths differ in the areas, these different absorption spectra can either be differentiated with the pixels or / and illuminated with a temporal change of different wavelengths or wavelengths in accordance with the different absorption spectra. As a result, the area of the semiconductor chip can be reduced in a particularly simple manner.
  • actively luminous substances e.g. chemical luminescence
  • the camera chip After application of the analyte such. B. urine, there are different color changes on the chip. This color change can then be read with the camera chip in transmitted light if the surface to which the substances are applied is transparent to the wavelengths of the light source minus the wavelengths absorbed by the substance.
  • the camera chip is in a light-tight housing and in this housing there is e.g. B. a white light source, which is then used for color detection. Daylight can also be used.
  • Wavelengths outside the visible range are particularly preferably used, which can then be read with the chip but not with the eye. This extends the selection of chemical substances considerably. Reference is made here to the general prior art, according to which different materials (semiconductors) can detect different wavelength ranges.
  • pixels can be left blank to allow calibration and measurement with e.g. B. To allow ambient light.
  • the chip will particularly preferably digitize and / or store the data and be connected to a PC via a USB connector.
  • the chemical substances which cause the color reaction can be applied directly to the chip in a preferred manner with the aid of printers, as are known from the field of biochip applications.
  • the chemical substances particularly preferably bind covalently to the surface.
  • the substances are applied to a carrier such as a film, paper strip or polymer, which is then z. B. placed on the chip or performed on this. It can particularly preferably be a light-tightly sealed chamber into which foils such as check cards can be inserted in the machine.

  • This additional coding can also be used on its own without coding the “application foils”.
  • coding in relation to other people or groups of people such as e.g. B. the treating doctor or the group of diabetes sufferers.
