“…Studies on the development and improvement of light-addressing technologies as well as their applications are accelerating fast and have extended into diverse directions in recent years. Various materials, such as InGaN [77], SnO x [78], indium gallium zinc oxide (IGZO) [79,80], fullerene (C 60 ) [81], layer-by-layer assembly of carbon dots and liquid exfoliated graphene [82], benzodithiophene-based polymer PTB7-Th/fullerene PC 71 BM [83], and nitrogen-doped graphene quantum dots [84], have been tested as a photosensitive active layer to replace silicon, as well as fluorographene [85] as a sensing membrane. Optimization of the sensor structure has also been studied to obtain a higher spatial resolution [86][87][88][89][90].…”

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.
