Summary: We report a facile synthesis of CuS and CdS nanoparticles using a cheap solution-processed chemical bath method forming heterogeneous nucleation. The optical band gap of CuS is estimated to be 2.10 eV, indicating its potential application in inexpensive photocatalysis and solar cells. The valence band and conduction band positions of CuS and CdS are evaluated using cyclic voltammetry curves. The narrow conduction and valence band offset potentials measured at the CuS/CdS heterojunction are encouraging factors for the photoelectrochemical (PEC) application. The current density vs potential plots (J-V) support the improved short-circuit current density and determined power conversion efficiency (PCE) of the CuS/CdS heterojunction.

Summary: A sandwiched photoelectrochemical immunosensor based on BiOI/Bi2S3/Ag2S was designed for the quantitative detection of CYFRA21-1 in serum. The intervention of narrow band gap Bi2S3 enhanced light absorption, while the matched band structure of BiOI, Bi2S3 and Ag2S promoted rapid electron transfer, ultimately improving the photoelectric signals. Additionally, sulfur and nitrogen co-doped carbon quantum dots with up-conversion luminescence, along with polydopamine combined secondary antibody labels, further enhanced the sensor's sensitivity.

Summary: Stretchable microcavity lasers fabricated on flexible PET substrate with the assistance of biocompatible SF film exhibit improved ASE performance of all-inorganic perovskite film. The optimized stack and good arrangement of CsPbBr3 QDs on top of SF film lead to lower threshold, higher slope efficiency, and larger gain coefficient. Moreover, the CsPbBr3 QD/SF film shows temperature-insensitive property and maintains low lasing threshold and high slope efficiency under mechanical bending.

Summary: In this study, a MnOx engineered Fe-N-C single-atom catalyst (Mn-Fe-N-C SAC) was developed to reduce oxidative corrosion and enhance the stability of the oxygen reduction reaction (ORR). The Mn-Fe-N-C SAC exhibited ultralow H2O2 yield and negligible potential shift after continuous potential cycles, demonstrating excellent ORR stability and improved activity compared to common Fe-N-C SACs. The interaction between MnOx and Fe-N-x sites enhanced the intrinsic activity of single iron sites, providing a promising solution for the stability issue of Fe-N-C SACs while maintaining high catalytic activity.

Summary: In this study, a single-atomic site catalyst (SASC) with excellent catalytic activity was designed to enhance the portable detection performance of herbicides. The catalyst exhibited superior peroxidase-like (POD-like) activity and was used as a label in lateral flow immunoassay (LFIA) for herbicide detection. The Fe-SASC-LFIA achieved a linear detection range of 1-250 ng/mL with a low limit of detection (LOD) of 0.82 ng/mL for 2,4-dichlorophenoxyacetic acid (2,4-D). The method demonstrated excellent specificity and selectivity towards 2,4-D and showed promising results in the detection of human urine samples, indicating its potential as a portable and high-sensitive point-of-care (POC) detection strategy for pesticide exposure evaluation.

Summary: Enzymes have great potential in various fields due to their high activity and specificity for catalysis under mild conditions. However, they struggle to adapt to different environments outside of their familiar biological conditions. Nanobiocatalysis, which integrates nanotechnology and enzymatic catalysis, aims to design biocatalysis based on materials science. Nano-integrated biocatalysis and bio-inspired nanocatalysis are two effective nanobiocatalytic systems that can meet different design needs, and their combination opens up even more possibilities. This review summarizes the types, constructions, and functions of nanobiocatalytic systems, analyzing the pros and cons of different strategies. Additionally, it highlights their applications in bioassay, biotherapy, and environmental remediation.
