Summary: This article introduces the engineering of nanobiosensors made from gold nanorods coated with an ultrathin layer of silica and biofunctionalized with antibodies. The use of gold nanorods for biosensing is limited due to the presence of a surfactant that complicates their bio-functionalization. However, when coated with a thin layer of silica, these nanomaterials exhibit improved sensitivity and analytical performances.

Summary: The ability to construct sensing platforms capable of selectively manipulating complex biological fluids is crucial for future advancements in healthcare. In this study, an electrochemiluminescence (ECL) transducer was developed by integrating protonated g-C3N4 and Ti3C2Tx MXene nanosheets, which exhibited enhanced charge injection/transfer and catalytic capacities for coreactant ECL. A mussel-inspired polydopamine was used as a surface-adherent substrate to coat the transducer, providing desired antifouling properties and ensuring minimal suppression of ECL performance. This highly integrated platform enabled high-performance exosome detection and tracking in a non-label manner. The study proposes a general design strategy for robust antifouling ECL sensing interfaces based on zwitterionic chemistries and provides new insights for the development of point-of-care and implantable ECL devices.

Summary: Carbon nitride (CN) is a promising 2D non-metal semiconductor material for photocatalysis and advanced oxidation processes (AOPs). This study synthesized crystalline carbon nitride (CCN) and used it to activate peroxymonosulfate (PMS) under visible light to degrade tetracycline (TC) efficiently. CCN exhibited superior PMS activation compared to traditional polymeric carbon nitride (PCN) due to its increased crystallinity and catalytic sites. The generation of singlet oxygen (1O2) was found to be the dominant reactive oxygen species in the CCN/PMS/visible light system. This work reveals the potential of CCN-based materials for practical wastewater treatment.
