Summary: Electrochemiluminescence (ECL) is chemiluminescence that is triggered by electrochemical reactions. ECL has become a powerful analytical technique widely used in biosensing and imaging due to its unique excitation mode and low background. Semiconductor quantum dots (QDs), as emerging ECL luminophores, have significant advantages over traditional molecular luminophores in terms of luminescence efficiency and signal modulation ability. Therefore, the development of an efficient ECL system using QDs as luminophores is important for improving the sensitivity and detection flux of ECL biosensors.

Summary: In this study, carbon nitride quantum dots (CNQDs) with efficient near-infrared electrochemiluminescence (NIR-ECL) and excellent biocompatibility were prepared as an emitter to construct an ultrasensitive regenerative biosensing platform for detection of microRNA-222 (miRNA-222). The introduction of electron-rich pyrimidine effectively increased the conjugation effect of electrons on triazine ring in CNQDs, resulting in red shift of ECL emission wavelength. An improved circular DNA walker was assembled by the catalytic ligation of T4 DNA ligase to enhance its stability and walking efficiency. By utilizing CNQDs as emitter and circular DNA walker as signal amplifier, a regenerative biosensor platform was developed for ultrasensitive detection of miRNA-222 with high sensitivity and successfully applied for detection in cancer cells lysate. This work opens up a promising approach for synthesizing efficient NIR-ECL CNQDs, reducing damage to organisms and achieving deeper tissue penetration, and provides a new method for biomarker detection and disease diagnosis.

Summary: Modular electrochemical production (MEP) system can separate the production of hydrogen and oxygen by using a redox mediator (RM). In this study, a Mott-Schottky Co9S8/Ni3S2 heterojunction was constructed as a RM to achieve the separation of hydrogen and oxygen in space and time in the MEP system. The MEP system involved a two-step electro-chemical-electrochemical (EC-EC) looping process, where the Co9S8/Ni3S2 redox reaction was paired with the hydrogen evolution reaction (HER) in step 1 and the oxygen evolution reaction (OER) in step 2. The Co9S8/Ni3S2 RM showed high area capacitance and stability, and the MEP system had high energy efficiency and could be powered by renewable solar energy.
