“…MXene is a promising two-dimensional material with abundant functional groups and metallic properties on its surface that facilitate strong interfacial contact with semiconductors through electrostatic adsorption, leading to the formation of photoactive heterostructures such as MXene/ Cu 2 O, 22 MXene/BiVO 4 . 23 Carbon nitride nanosheet (C 3 N 4 ) is considered as one of the most potential photoactive materials due to its high reduction potential, visible light absorption, and good photo and thermal stability. 24 However, the inherent poor conductivity, fast carrier recombination rate, insufficient light absorption, and low photoactivity limit its applications.…”

In this paper, a photoelectrochemical (PEC)-surfaceenhanced Raman scattering (SERS) dual-mode biosensor is constructed coupled with a dual-recognition binding-induced DNA walker with a carbon nitride nanosheet (C 3 N 4 )/MXene-gold nanoparticles (C/M-Au NPs) accelerator, which is reliable and capable for sensitive and accurate detection of Staphylococcus aureus (S. aureus). Initially, a photoactive heterostructure is formed by combining C 3 N 4 and MXene via a simple electrostatic self-assembly as they possess well-matched band-edge energy levels. Subsequently, in situ growth of gold nanoparticles on the formed surface results in better PEC performance and SERS activity, because of the synergistic effects of surface plasmon resonance and Schottky barrier. Furthermore, a three-dimensional, bipedal, and dualrecognition binding-induced DNA walker is introduced with the formation of Pb 2+ -dependent DNAzyme. In the presence of S. aureus, a significant quantity of intermediate DNA (I-DNA) is generated, which can open the hairpin structure of Methylene Bluetagged hairpin DNA (H-MB) on the electrode surface, thereby enabling the switch of signals for the quantitative determination of S. aureus. The constructed PEC-SERS dual-mode biosensor that can be mutually verified under one reaction effectively addresses the problem of the low detection accuracy of traditional sensors. Experimental results revealed that the effective combination of PEC and SERS is achieved for amplification detection of S. aureus with a detection range of 5−10 8 CFU/mL (PEC) and 10−10 8 CFU/mL (SERS), and a detection of limit of 0.70 CFU/mL (PEC) and 1.35 CFU/mL (SERS), respectively. Therefore, this study offers a novel and effective dual-mode sensing strategy, which has important implications for bioanalysis and health monitoring.

Halogen, bromine (Br)-doped layered graphitic carbon nitride (gCN) nanosheets are constructed for a novel electrochemical detection of dopamine. The Br is successfully immobilized on gCN host lattice, in which Br provides an N-vacancy for -C-N bonding to improve electron transfer and enhance its electrocatalytic properties. The prepared nanosheets are studied by various analytical analyses and the electrochemical behavior of the designed electrode is studied using cyclic voltammetry. The Br-gCN decorated screen-printed carbon electrode (SPCE) has superior electrochemical activity and is stable during exposure to varied pH but exhibited better catalytic activity at pH 7. The Br-gCN/SPEC electrodes and their high electrocatalytic performance are used for the detection of dopamine with a lower limit of detection (LoD) of 5 nM concentration. The Br-gCN decorated electrodes exhibited satisfactory results for cyclic stability (up to 100th cycle), repeatability (up to six cycles), reproducibility of similarly constructed 6 electrodes, and their electrochemical performance. Furthermore, the fabricated sensor also exhibited a better recovery (> 80%) for real-time urine sample analyses.
