ABSTRACT:
Device, kit and method of using same to detect analytes such as nucleic acids are described. An excitation source, preferably a nitride-based LED, emits light capable of being absorbed by luminophores. Sensors are stably attached, preferably via covalent or ionic bonds, to a surface within the device, such as the surface of the excitation source that is exposed to the sample. When a complex is formed between the sensors and the analyte, the luminophores emit light or emit light of a different wavelength, thereby signaling the presence or quantity of the analyte.
