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.

Abstract: A method for amplifying nucleic acids by a polymerase chain reaction in a reaction volume heated using electrical energy. In at least one of the passages of the amplification cycle of the polymerase chain reaction, the ratio of the electrical energy used in the denaturation step to heat the reaction volume to the size of the reaction volume is less than 20 Joule per milliliter. Further shown is a method of amplifying nucleic acids in a reaction volume by using a device that includes a reaction vessel and a heating means with at least one heating element in contact with the reaction volume where at least one heating element is conjugated to oligonucleotides. Also shown is a device for the amplification of nucleic acids in a reaction volume including a reaction vessel for receiving the reaction volume and a heating means consisting of at least one heating element contacting the reaction volume.
