Article Abstract
Sulfur dioxide (SO) is emerging as a double-edged molecule, while plays vital roles in food and biological system. However, the fast, highly sensitive, and versatile fluorescent probe still remains a tough challenge among current reports. Herein, we developed a novel aggregation-induced emission (AIE) fluorescent probe TPE-PN for specifically sensing SO derivatives with high sensitivity (150 nmol/L) and rapid response time (10 s) based on intramolecular charge transfer (ICT) mechanism. And the fluorescence at 575 nm decreased tremendously with 31-fold after the probe was treated with HSO. Employing the probe, the accurate analysis of HSO was successfully realized in food samples, cells, plant tissues, and zebrafishes. Furthermore, we successfully demonstrate the eruption of SO derivatives within plant during drought and salt stress processes. Therefore, probe TPE-PN illustrates significant potential for applications in food analysis and monitoring of SO derivatives levels in biological systems under stress conditions.

Significance: The spatial and temporal distribution of fluorophore fractions in biological and environmental systems contains valuable information about the interactions and dynamics of these systems. To access this information, fluorophore fractions are commonly determined by means of their fluorescence emission spectrum (ES) or lifetime (LT). Combining both dimensions in temporal-spectral multiplexed data enables more accurate fraction determination while requiring advanced and fast analysis methods to handle the increased data complexity and size.

Labeling the plasma membrane for advanced imaging remains a significant challenge. For time-lapse live cell imaging, probe internalization and photobleaching are major limitations affecting most membrane-specific dyes. In fixed or permeabilized cells, many membrane probes either lose signal after fixation or fail to remain localized to the plasma membrane.

As a cutting-edge super-resolution imaging technique, structured illumination microscopy (SIM) has been widely used in cell biology research, especially in the analysis of subcellular organelles and monitoring of their dynamic processes. Through multiple illumination and reconstruction processes, SIM breaks through the resolution limitations of traditional microscopes and can observe the fine structures within cells in real time with nanoscale resolution. This provides strong technical support for in-depth analyses of molecular mechanisms, organelle functions, signaling networks, and metabolic regulatory pathways within cells.

Controlled photoactivation is an auspicious and emerging approach in super-resolution microscopy, offering virtually zero background signal from the marker prior to activation. Pyronins are well-established fluorophores, but due to their inherent intercalating tendency towards nucleic acids, their use has been mostly avoided in super-resolution microscopy. Here, we describe a new class of diaryl ether and diaryl silane molecules that upon photoactivation close into fluorescent (silicon-)pyronins and term them Pyronin Upon Light Irradiation (PULI).

Eutectogels have emerged as versatile materials for wearable electronics, optical sensors, and biomedical applications. This study introduced the first investigation of microenvironmental basicity in poly(vinyl alcohol)/choline chloride (PVA/ChCl) eutectogels using lumichrome as a fluorescent probe. The incorporation of ChCl was demonstrated to enhance the microbasicity of PVA films, as evidenced by the significant promotion of lumichrome deprotonation.
