“…Another promising application is neurotransmitter detection of serotonin [101], dopamine [102], [103], and acetylcholine [104], [105]. LODs in EGFETs as low as 1 pM [102] have been reported for dopamine which outperform FET and OECTs [106]- [109].…”

Low operating voltages, rapid response, and high-throughput fabrication compatibility are key advantages for the development of electrolyte-gated field effect transistors (EGFETs) for biological sensing. Among the key components in EGFET biosensors, electrolyte materials are relatively less investigated, especially alternatives to water-based liquid electrolytes such as ionic liquids, ion gels, polyelectrolytes, and solid polymer electrolytes. These electrolytes enable portable devices and environmental stability superior to their water-based liquid alternatives. In this review, we offer an up-to-date evaluation of the state of EGFET research and gauge the strengths and limitations of high-performance electrolytes for use in EGFET biosensor applications as well as the potential for computer-aided design of such sensing platforms. The recent progress of EGFET biosensors for some popular analytes are reviewed and the performance of these alternative electrolytes in transistor biosensing is assessed. The challenges and opportunities for electrolytes in EGFETs are discussed for future research directions in this field.

“…H. Zhang et al [ 111 ] demonstrated that the use of polymorphic anatase-rutile TiO 2 nanofibers to build FET showed better transistor characteristics because of a strong synergistic effect compared with pure anatase and rutile TiO 2 nanofibers. BioFET created by S. Veeralingam and S. Badhulik [ 97 ] based on β–Bi 2 O 3 nanofibers for the detection of serotonin exhibited sensitivity of 51.64 μA/nM over a range of 10 nM −1 μM and a limit of detection of 0.29 nM. Moreover, it maintained excellent sensitivity, stability and reproducibility with a rapid response time of 0.8 s. Using the electrospinning method, K.C.S.…”

The growing scientific interest in one-dimensional (1D) nanostructures based on metal-oxide semiconductors (MOS) resulted in the analysis of their structure, properties and fabrication methods being the subject of many research projects and publications all over the world, including in Poland. The application of the method of electrospinning with subsequent calcination for the production of these materials is currently very popular, which results from its simplicity and the possibility to control the properties of the obtained materials. The growing trend of industrial application of electrospun 1D MOS and the progress in modern technologies of nanomaterials properties investigations indicate the necessity to maintain the high level of research and development activities related to the structure and properties analysis of low-dimensional nanomaterials. Therefore, this review perfectly fits both the global trends and is a summary of many years of research work in the field of electrospinning carried out in many research units, especially in the Department of Engineering Materials and Biomaterials of the Faculty of Mechanical Engineering and Technology of Silesian University of Technology, as well as an announcement of further activities in this field.

“…In this regard, β‐Bi 2 O 3 , tetragonal crystal structured metal‐oxide semiconductor, has attracted extensive attention because of its excellent electrical and optical properties such as wide band‐gap, high absorption coefficient, and acceptable photoconductivity. [ 6 ] UV‐blocking property for β‐Bi 2 O 3 will result from its photochemical stability and direct bandgap. However, β‐Bi 2 O 3 based photodetectors have not been widely studied due to its poor conductivity.…”

“…However, β‐Bi 2 O 3 based photodetectors have not been widely studied due to its poor conductivity. [ 6,7 ] β‐Bi 2 O 3 nanofibers synthesized with the electrospinning technique showed a significant improvement in its conductive property because they have a larger aspect ratio and high surface area to volume ratio that helps to obtain fast recovery time and high photo response for UV light detection. [ 8 ] As mentioned earlier, p–n junction formation is highly advantageous due to a built‐in electric field that automatically separates generated electron−hole pairs.…”

Recently reported ultraviolet (UV) detectors majorly focus on exploration of photodetection properties like photon absorption and electron‐hole pair generation to improve the photoresponsivity. However, UV sensors also have a potential advantage of monitoring the excessive UV exposure on skin. In this work, bismuth oxide/SnO2 quantum dots (QDs) vertical‐junction‐based self‐powered UV photodetector and optical UV filter are demonstrated. β‐Bi2O3 nanofibers are synthesized via electrospinning technique and SnO2 QDs are synthesized using a facile, single step hydrothermal process. Detailed morphological studies reveal the formation of 1D‐Bi2O3 and 0D‐SnO2. The fabricated self‐powered Bi2O2/SnO2‐based p–n heterojunction device exhibits a maximum responsivity of 62.5 µA W−1 and specific detectivity (D*) of 4.5 × 109 Jones attributing to the high absorption coefficient of β‐Bi2O2 nanofibers and SnO2 QDs in the UV region. Further, the 1D β‐Bi2O3 nanofibers and 0D SnO2 QDs are coated onto disposable cloth substrate to fabricate the UV optical filter which exhibits an exceptional ultraviolet protection factor of 159 and the photodetector device demonstrates high stability and reproducibility even after 1000 bending cycles. The strategy outlined here paves the way for development of bifunctional, cost‐effective design and construction of wearable UV sensors and protective devices for advanced nano‐electronic applications.
