Recent Advances in Photoelectrochemical Sensing: From Engineered Photoactive Materials to Sensing Devices and Detection Modes

“…Apart from these heterojunctions, other novel semiconductor-semiconductor heterojunctions have also been reported for PEC sensing in recent years, such as ZnIn 2 S 4 / CdS, 102 Bi 2 S 3 /Bi 2 WO 6 , 103 Semiconductor-Carbon Heterojunction. The most common carbon materials used for constructing the semiconductor-carbon heterojunction are graphene oxide, 107 reduced graphene oxide, 108 graphene hydrogel, 109 multiwalled carbon nanotubes (MWCNTs), 110 and single-walled carbon nanotubes (SWCNTs). 111 The innate advantages of these carbon materials are the strong chemical stability, high specific surface area, and superior electron mobility.…”

Photoelectrochemical Immunoassays

“…150 Graphene and its derivatives, as interesting two-dimensional (2D) carbon nanomaterials, have also been used in this field. For example, reduced graphene oxide (rGO) has been extensively used for PEC immunoassays of PSA, 69,118 indole-3-acetic acid, 87 CEA, 91,129,134 microcystin-LR, 146 α-fetoprotein (AFP), 155 and cancer antigen 125 (CA 125), 154 while graphene oxide (GO) has also been used for PEC immunoassay of carcinoembryonic antigen. 80 In addition to graphene, some other carbon materials, e.g., carbon nanotubes, 56,112,130,131,153 mesoporous carbon, 148 fullerene C60, 56,101 and carbon nanohorns, 59 have also been applied.…”

Multiparametric modulation of magnetic transduction for biomolecular sensing in liquids

“…Interestingly, transduction methodologies capable of supplying multiparametric sensitivity gain in versatility for adequate biomarker detection in liquids under experimental circumstances (i.e., biomarker concentration). 4 Recent progress in nanoscience and nanotechnology offers novel transducing potential, such as photoelectrochemical, 5,6 optical, 7,8 colorimetric, [9][10][11] photothermal, 12 or magnetic 13,14 signal-based methods. Indeed, nanoscale transducers have attracted great attention thanks to their ability to detect biomarkers in biological fluids at concentrations of clinical relevance.…”
