  • Patent number: 11326205
    Abstract: The invention relates to a method for the duplication of nucleic acids by means of a polymerase chain reaction, in the case of which a cycle consisting of the steps of denaturing, annealing and elongation is repeatedly performed. In one embodiment, in at least one passage of the cycle, the quotient of the duration of effect tA and the reaction volume Vr irradiated by the energy source is less than 1 seconds per microliter. In another embodiment, in at least one passage of the cycle, the ratio of the duration of effect (tA) and the duration of the PCR cycle (tc) is less than 20%. In certain embodiments, the yield (g) of nucleic acids at the end of at least one of the passages of the cycle is less than 80% of the nucleic acids present at the start of the passage.

  • Patent number: 10619151
    Abstract: A method for extracting a nucleic acid from a sample liquid comprises providing a heating element and providing an extraction nucleic acid that is bound to the heating element and/or providing the extraction nucleic acid such that the extraction nucleic acid binds to the heating element. The extraction nucleic acid is at least partly complementary to the nucleic acid. The method further comprises bringing the heating element into contact with the sample liquid such that the nucleic acid at least partly binds to the extraction nucleic acid, and separating the heating element from the sample liquid such that the nucleic acid bound to the extraction nucleic acid remains at the heating element. Additionally, the method comprises bringing the heating element into contact with a reaction solution, and heating the heating element to at least a denaturing temperature of the nucleic acid.

  • Patent number: 10544450
    Abstract: The invention relates to a method for the duplication of nucleic acids by means of a polymerase chain reaction, in the case of which a cycle consisting of the steps of denaturing, annealing and elongation is repeatedly performed. In one embodiment, the yield (g) of specimens of a nucleic acid to be duplicated, at the end of at least one passage of the cycle, is less than 80 percent of the specimens of the nucleic acid present at the beginning of said passage and, in the case of at least one passage of the cycle, the reaction time (tA) is less than one second. In addition, in a further embodiment, the number (k) of passages of the cycle of the polymerase chain reaction is greater than 45 and/or in at least one of the passage the cycle time tc is less than 20 seconds.

  • Patent number: 9926594
    Abstract: A method for the amplification of nucleic acids, in which nanoparticles in a reaction volume transfer heat to their environment through excitation. The method comprises a step of providing nanoparticles with the nucleic acids in a reaction volume and one or more heating steps. In at least one of the heating steps, the heating is achieved at least partially through the excitation of the nanoparticles. The interval of the excitation is chose to be shorter or equal to a critical excitation time.

  • Patent number: 9890415
    Abstract: A method for detecting at least one nucleic acid in a solution, comprising the steps of: providing at least one dye, wherein the solution and/or a reaction vessel, wherein the solution is present, comprises the dye and wherein the at least one dye is adapted to emit emission light due to an optical excitation by excitation light; providing at least one absorber in the solution, wherein the absorber is adapted to cause an attenuation of the emission light and/or the excitation light and wherein the attenuation is influenced by a bonding of the at least one absorber to the nucleic acid; and radiating excitation light into the solution and measuring an intensity of the emission light; wherein the attenuation of the emission light and/or the excitation light by the at least one absorber occurs independently of a quantum yield of the at least one dye.
