    Abstract: A grating-based sensor is disclosed that has a grating structure constructed and designed for both evanescent resonance (ER) fluorescence detection and label-free detection applications. Some embodiments are disclosed which are optimized for ER detection in an air mode, in which the sample is dry. Other embodiments are optimized for ER detection in liquid mode, in which the sample is suspended in liquid medium such as water. One and two-dimensional gratings are also disclosed, including gratings characterized by unit cells with central posts, central holes, and two-level, two-dimensional gratings. A readout system for such sensors is also disclosed. One embodiment includes a first light source optimized for collecting label-free detection data, a second light source optimized for collecting ER fluorescence amplification data, and at least one detector. In one embodiment, the detector is an imaging system and includes a CCD camera for collecting both ER and label-free data. In other embodiments, the at least one detector takes the form of a spectrometer for collection of label-free data and a photomultiplier for collecting ER data. In other embodiments, a single light source such as a tunable laser or broad band light source is used.

One and two-dimensional gratings are also disclosed, including gratings characterized by unit cells with central posts, central holes, and two-level, two-dimensional gratings. A readout system for such sensors is also disclosed. Various applications for the biosensors are described, including cell-based assays for assessing the effect of drug compounds on cell function. A biosensor embodiment optimized for a luminescent response at two different wavelengths is also described. Such luminescent response could be produced by fluorescence (either native or from an attached fluorophore), phosphorescence, chemi-luminescence, or other luminescence technology. Two different luminescence technologies could be combined on the same biosensor chip.
