Abstract: The present invention relates to a device for the amplification and for the detection of nucleic acids comprising a temperature controlling and/or regulating unit; a reaction chamber containing a support with a detection area, on which a compound library is immobilized, wherein the temperature in the reaction chamber can be controlled and/or regulated by means of the temperature controlling and regulating unit; and an optical system, by means of which the time-dependent behavior of precipitate formations on the detection area is detectable. Methods of using the device are also disclosed.

Abstract: Disclosed are devices for holding a substance library carrier, and which are useful in conducting reactions in which binding between complementary molecules is measured qualitatively or quantitatively. Also disclosed are methods for conducting such reactions in the device.

Abstract: Disclosed is a method for qualitative and/or quantitative detection of nucleic acid molecules amplified in an amplification reaction such as PCR. The change of the mass of oligonucleotides in an amplification solution, comprising the mass of target DNA and optionally, the mass of oligonucleotide primers, is determined during the amplification reaction. Also disclosed is a device for conducting the method.
