Photoelectrochemical sensing has developed rapidly in the past decade because of its inherent advantages of economic devices and low background noise. However, traditional assembly of photoelectric beacons, probes, and targets on the ITO electrode solid−liquid interface inevitably leads to time-consuming, limited selectivity, poor stability, and nonreproducibility. To overcome these drawbacks, in this work, a unique splittype PEC aptasensor for carcinoembryonic antigen (CEA) was developed in virtue of the sandwich-like structure comprised of magnetic-optical Fe 3 O 4 @SiO 2 @CdS-DNA 1 , CEA aptamer, and signal element SiO 2 −Au-DNA 2 . The sandwich-like structure is easily formed in the liquid phase and can be triggered by competition from low-abundance CEA, resulting in dissociation. By further photocurrent measurement in pure phosphate buffer saline (PBS), coexisting species can be effectively removed from the modified electrode, improving selectivity, stability, and repeatability. These advantages benefit from the preparation of uniform and monodispersed Fe 3 O 4 @SiO 2 @CdS and SiO 2 −Au particles, DNAs assembly, and an elegant design. Additionally, the as-designed signal-on PEC aptasensor is highly sensitive, short time-consuming, and economical, enabling the detection of CEA in serum specimens. It not only provides an alternative to CEA immunosensors, but also paves the way for high-performance PEC aptasensors.

“…Therefore, it can be seen that the photocatalytic degradation activity was improved with the introduction of GQDs. [ 34,35 ] Moreover, not only can the GQDs‐BWO‐PAM hydrogel exhibit similar photocatalytic performance as GQDs‐BWO, but also reduces the difficulty of recycling the catalyst powder.…”

It is demonstrated that, by using the electronic reconstruction of ultrathin Bi2WO6 (BWO) nanosheets with graphene quantum dots (GQDs) upon a unique process of laser irradiation in liquid (LAL), a kind of GQDs modified BWO nanosheets under metastable state were synthesized, which performed excellent visible‐light piezo‐photocatalytic organics degradation. Furthermore, using commercial cpolyacrylamids (PAM) as the additional materials, a kind of electronic reconstruction GQDs‐BWO nanosheets hydrogel was achieved by dispersed the functionalized powders into a super absorbent polymers (SAPs) system upon in situ polymerization method, which showed that it is a bracing idea to use SAPs for water decontamination reactors to enable full use of vibration energy synergistic with light of nature to driven pollution degradation. First‐principles calculation was also simultanously performed in this study. This study may provide a new enlightenment on fabricating novel 2D nanomaterials hydrogel for efficient effluent purification and potentially other environmental or energy applications.

“…Therefore, metal materials with high conductivity and catalytic performance can easily be mixed or doped with carbon fiber to form composite materials, which often have synergistic effect and stronger electrochemical performance. The metals like Cu, Ni, Mn, Co, Sn, Mo and their oxides or sulfides with excellent properties have attracted the attention of researchers [4–6] . Among them, SnO 2 is a good conductive material, which has good conductivity in aqueous solution.…”

SnO2‐CNF was prepared by coaxial blending technology, and MoS2 was grown uniformly on SnO2‐CNF composite by adding a hydrothermal post‐treatment step. The uniform distribution of MoS2 on one‐dimensional SnO2‐CNF can effectively establish a layered three‐dimensional structure. Accordingly, the prepared MoS2‐coated SnO2‐CNF composite material has higher surface area and more active sites to obtain better electrochemical performance. We constructed an electrochemical sensor within the composite material with enhanced performance to realize the simultaneous and highly sensitive detection of phenacetin and indomethacin. The sensor has linear ranges of 0.050–7200 μM and 0.05–500 μM, respectively, and the detection limits were 0.016 μM and 0.013 μM. Furthermore, the sensor has good anti‐interference ability and stability, which also achieves good recovery rate in the actual sample detection.
