A biochemical arrayed sensor based on optical resonance technology and characterized by the dispersed positioning and properties of individual sensing units is discussed. Fabrication simplicity and reusability of the sensor as well as robustness of signal excitation and possibility for parallel probing are among the advantageous features for the implementation of optical resonance sensing for practical-oriented tasks. The arrayed sensor applicability, performance, and correspondence between the responses and analytical models are analyzed on the example of biochemical components' monitoring. The efficient regeneration of sensing properties realized by cleaning of the reacting surface allows to perform multiple sensing tasks in a single experimental run. The sensor interrogation approach based on the dispersion of the sensing units' spectral characteristics is discussed. © 2001-2012 IEEE.
