Rechargeable zinc-air batteries(ZABs) have recently drawn great attention in energy research due to their high theoretical capacity,low costs, and inherently safe nature [1–3]. However, the sluggish cathode reactions necessitate the developm.nt of bifunctional oxygen electrocatalysts with lower ΔE indicator values. The ΔE indicator is comm.nly employed to quantitatively evaluate the electrocatalytic activity of a bifunctional oxygen electrocatalyst,representing the overall overpotential from oxygen reduction reaction(ORR) to oxygen evolution reaction(OER).

Sequence-activated chemilum.nescence(CL) technique offers a unique approach to detecting specific biomolecules or cellular events with high sensitivity and spatial resolution. The fundam.ntal principle behind sequence-activated CL probes involves tailoring highly-controllable CL signals in response to specific sequences or events of interest, thus enabling high-contrast signals under complex physiological conditions. This sequential activation could be triggered by enzymes, reactive oxygen species(ROS), biothiols or changes in the microenvironm.nt. These unique sequence-activated CL probes bestow several advantages, including m.nimal background, deep-tissue penetration, and the ability of non-invasive or m.nimally invasive detection. The sequence-activated CL techniques represent a significant advancem.nt in molecular imaging and diagnostics. In this m.ni-review, we focus on the latest developm.nts in sequential CL probes, addressing the technical challenges and discussing the future trajectory by harnessing CL signaling and molecular recognition.
