“…Using the present sensor, we can capture real-time optical and electric images of neural activity. Sawada et al have been working on multifunctional image sensors with electric sensing functionality based on ISFET-type configuration [6,7,8] (see Figure 1 (c)). They developed optical + pH multifunctional image sensors.…”

In this review, the concept, design, performance, and a functional demonstration of multifunctional complementary metal-oxide-semiconductor (CMOS) image sensors dedicated to on-chip biosensing applications are described. We developed a sensor architecture that allows flexible configuration of a sensing pixel array consisting of optical and electric sensing pixels, and designed multifunctional CMOS image sensors that can sense light intensity and electric potential or apply a voltage to an on-chip measurement target. We describe the sensors’ architecture on the basis of the type of electric measurement or imaging functionalities.

“…Sawada et al 107 presented an interesting device that can sense both photons and ions on the same pixel for the nearsimultaneous detection of a photosignal and ion concentration. They used different mechanisms for photosensing and ion sensing and detected each parameter in a separate time period.…”

“…Figure 12 shows the concept, schematic diagram, and photograph of the device. 107 The performance of each sensing mechanism was tested using solutions of various pH and under several light intensities. The output of each sensor was unaffected by the other parameter, i.e., there was no cross-talk between the two sensors.…”

Fluorescence-based cross reactive sensor arrays have experienced significant development in the last decade because of the advantages that they can offer with respect to other transduction mechanisms, in terms of the usual performance parameters such as sensitivity, selectivity and so on. From this point of view, a great impulse to this development has been due to the realization of novel transduction platforms, which has also taken advantage of the development of consumer electronics such as digital scanners, cameras, and screens, allowing the realization of low cost sensing layers suitable for many practical applications. This possibility, combined with continuous optimization of sensing material properties, the possible preparation of arrays with a high number of individual sensing elements and pattern recognition data analysis, has led to novel opportunities for the creation of luminescence based sensor arrays with improved capabilities. Herein we report on the development of these devices witnessed in the last decade, dividing the developed devices according to their exploitation in gaseous or in solution phase.
