Abstract: A method for extracting a target nucleic acid from a sample liquid includes providing a heating device having a heating element in contact with the sample liquid. The heating element is conjugated with at least one functional nucleic acid. The functional nucleic acid is adapted to hybridize to the target nucleic acid and bind the target nucleic acid to the heating element. Further, the method includes generating relative movement between the heating element and the sample liquid and extracting the target nucleic acid from the sample liquid by separating the heating element from the sample liquid.

Abstract: Provided is a method for extracting a target nucleic acid (12) from a sample fluid (30). The method comprises providing a sample fluid (30) comprising the target nucleic acid (12) in a reaction container (22) and providing magnetic microparticles (10) in the sample fluid (30), each functionalized with at least one extraction nucleic acid (16), wherein the extraction nucleic acids (16) are at least partially complementary to the target nucleic acid (12). Further, the method comprises hybridizing at least a part of the target nucleic acid (12) with one of the extraction nucleic acids (16) and binding the target nucleic acid (12) via the extraction nucleic acid (16) to one of the magnetic microparticles (10). Furthermore, the method comprises providing a magnetic field in the reaction container (22) in such a manner that at least a part of the magnetic microparticles (10) associated with the target nucleic acid (12) sediments on a container wall (22a, 22b, 22c) of the reaction container (22).

Abstract: A device for extracting a nucleic acid from a sample liquid includes a heating element configured to be connected to an extraction nucleic acid. The extraction nucleic acid is at least partly complementary to the nucleic acid to be extracted from the sample liquid. The heating element is heatable to a temperature that is equal to or higher than a denaturing temperature of the nucleic acid bound to the extraction nucleic acid.

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.
