Abstract
Methods and systems for highly-sensitive label-free multiple analyte sensing, biosensing, and diagnostic assay are disclosed. The systems comprise an on-chip integrated two-dimensional photonic crystal sensor chip. The invention provides modulation methods, wavelength modulation and intensity modulation, to monitor the resonance mode shift of the photonic crystal microarray device and further provides methods and systems that enable detection and identification of multiple species to be performed simultaneously with one two-dimensional photonic crystal sensor chip device for high throughput chemical sensing, biosensing, and medical diagnostics. Other embodiments are described and claimed.
