Abstract

A method of detecting locations on a nucleic acid probe array at which hybridization occurs between targets in a fluid sample and nucleic acid probes disposed on a surface of the nucleic acid probe array, comprising: measuring the temperature at a plurality of locations on the surface of the nucleic acid probe array; applying an oscillating level of energy to the surface of the nucleic acid probe array, thereby causing the temperature at the surface of the nucleic acid probe array to oscillate; and detecting a decreased range of temperature oscillation at least one of the plurality of locations on the nucleic acid probe array, thereby indicating an increased heat capacity caused by latent heat of hybridization between at least one target in the fluid sample and at least one nucleic acid probe disposed on a surface of the nucleic acid probe array.
