Recently, radioactive pollutants have garnered significant attention within the realms of environmental science and public safety, such as nuclear energy (, uranium), radiation therapy (, I), and earthquake monitoring (, radon), exerting multifaceted impacts on human health and ecosystems. Therefore, the development of accurate detection technologies for key radioactive elements is of paramount importance and is also an important guarantee for ensuring public safety and comprehensively promoting harmonious coexistence between humans and nature. Luminescent probes represent a class of detection methods for radioactive elements, characterized by high sensitivity, simplicity, and visualization. This article reviews the development and recent advances of luminescent probes for radioactive elements, such as uranium, iodine, strontium, cesium, and radon in the environment, and discusses their application prospects and potential contributions in the fields of environment as well as public safety.

Recently, metal-organic frameworks (MOFs) have shown high potential in the field of sensing. However, fluorescent-based detection with MOFs in solution needs complex pre-treatments and has stability issues, complicating measurements and handling for sensing applications. Here, an easy-to-handle and low-cost strategy is introduced to convert MOF-based sensing from solution to surface using scanning probe lithography.

Optical imaging offers high sensitivity and specificity for noninvasive cancer detection, but conventional techniques suffer from limited probe accumulation, tissue autofluorescence, and poor depth resolution. Afterglow luminescence overcomes autofluorescence by emitting persistent light after excitation, yet its utility in vivo remains hindered by weak tumor enrichment and two-dimensional readouts lacking spatial context. Here, we report luminescent-magnetic nanoparticles (LM-NPs) coencapsulating luminescent trianthracene (TA) molecules and iron oxide cores within the amphiphilic polymer pluronic-F127.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by β-amyloid (Aβ) deposition, imposing significant social and economic burdens globally. Despite extensive efforts have been devoted to developing fluorescent probes for Aβ imaging, further improving the luminescent efficiency of prevailing probes still remains a significant challenge. Herein, we investigated the inner mechanism of constructing high-efficient Aβ probes via a structural cyclization strategy.

A novel aggregation-induced emission (AIE) system with superior performance was successfully developed through local chemical modification from thiophene to thiophene sulfone. This approach, leveraging easily accessible tetraphenylthiophene precursors, dramatically enhances the photophysical properties in a simple oxidation step. Notably, the representative 2,3,4,5-tetraphenylthiophene sulfone (3c) demonstrates remarkable solid-state emission characteristics with a fluorescence quantum yield of 72% and an AIE factor of 240, substantially outperforming its thiophene analog.

Adenosine triphosphate (ATP) is a critical biomolecule in cellular energy metabolism, with abnormal levels in the bloodstream linked to pathological conditions such as ischemia, cancer, and inflammatory disorders. Accurate and real-time detection of ATP is essential for early diagnosis and disease monitoring. However, conventional biochemical assays and other techniques suffer from limitations, including invasive sample collection, time-consuming procedures, and the inability to provide dynamic, monitoring.
