A chemical imaging sensor is a field-effect-based semiconductor sensor, capable of label-free imaging of ion distributions in a solution. The sensor has attracted much interest owing to its simple structure and diverse fields of application of bioimaging. In this article, the principle and development of the chemical imaging sensor are summarized, compared with those of other labelfree imaging sensors. Bio-imaging applications of the chemical imaging sensor to ion diffusion, enzymatic reaction, and metabolic activities of microorganisms are also reviewed.

“…Previously, we proposed and presented a charge-transfer type pH sensor, which could transduce a chemical potential through pH to determine charge quantity [1]. The charge-transfer type sensor was applied as a highly sensitive ion sensor [2], as a fused sensor for optical and ion sensing [3], and as 32×32 arrayed pH imaging sensor [4]. In addition, we developed a multi-wavelength detection sensor [5,6], which could be applied for the detection of fluorescence.…”

A fused pH and fluorescence sensor is proposed, and a prototype has been fabricated using CMOS silicon integrated circuit technology. Fluorescence intensity and pH can be detected at the same pixel for the first time. In the proposed device, a pH sensor which uses CCD image sensor technology and a filter-less fluorescence detection sensor are fused in the same pixel, enabling fluorescence and pH signals to be detected simultaneously in the same sensing area.
