“…Optimization of the sensor structure has also been studied to obtain a higher spatial resolution [86][87][88][89][90]. As for the applications, many studies are directed to biosensing applications, including the detection of DNA hybridization [56,91], determination of glucose [92,93] and okadaic acid [94], as well as immunoassays of antigens [95]. Many studies are especially oriented to the detection of clinical biomarkers such as circulating tumor cells [96], alphafetoprotein [97], 1,5-anhydroglucitol [98], glypican-3 [99], and low-density lipoprotein [100].…”

The artificial olfactory image was proposed by Lundström et al. in 1991 as a new strategy for an electronic nose system which generated a two-dimensional mapping to be interpreted as a fingerprint of the detected gas species. The potential distribution generated by the catalytic metals integrated into a semiconductor field-effect structure was read as a photocurrent signal generated by scanning light pulses. The impact of the proposed technology spread beyond gas sensing, inspiring the development of various imaging modalities based on the light addressing of field-effect structures to obtain spatial maps of pH distribution, ions, molecules, and impedance, and these modalities have been applied in both biological and non-biological systems. These light-addressing technologies have been further developed to realize the position control of a faradaic current on the electrode surface for localized electrochemical reactions and amperometric measurements, as well as the actuation of liquids in microfluidic devices.
