It is evident that developing a detection tool for SO2 derivatives in biological systems and pH fluctuations in food samples is of great significance. Fluorescent probes have specificity and high selectivity, enabling sensitive determination SO2 derivatives and on-site detection pH changes. Therefore, a dual-functional near-infrared fluorescent probe (probe-OH) for monitoring SO2 derivatives and colorimetric sensing pH levels was constructed. The probe-OH enables rapid and sensitive determination of HSO3-and \"naked eye\" observation pH due to its high sensitivity and excellent reversibility performance. Additionally, a smartphone application platform was successfully constructed for colorimetric recognition pH level. Meanwhile, probe-OH combined with test strips assist in colorimetric evaluation of the pH changes in meat products during spoilage, and determine the pH value in actual beverages.More importantly, the probe-OH with higher fluorescence efficiency and excellent biocompatibility, will be further applied in the imaging of liver cancer cells.

The photophysical behavior of the dyes was investigated in solvents of varying polarity, revealing distinct solvatochromic effects and enhanced emission efficiency, particularly for diphenylamine-substituted derivatives. Density Functional Theory (DFT) calculations supported experimental observations, confirming frontier orbital distributions consistent with ICT.

To explore practical utility, the most emissive dyes were successfully embedded into oxadiazole-based microparticles and tested for latent fingerprint development on porous and non-porous surfaces. Additionally, water-based ink formulations prepared from these dyes demonstrated excellent stability and visibility under UV light, making them suitable for covert writing and anti-counterfeiting applications.

In this study, we developed a polydopamine stabilized silver nanoparticles (PDA-AgNPs) as a colorimetric probe for the rapid, simple, sensitive and selective determination of CN- ions. The PDA-AgNPs were synthesized and characterized using UV-Vis, TEM, XRD, FT-IR, DLS and Zeta potential measurements. On successive additions of CN- ions, the surface plasmon resonance (SPR) band of PDA-AgNPs at 392 nm was progressively decreased, accompanied by a visible color change from yellow to colorless. This response was attributed to the formation of [Ag(CN)2]- complexes in the presence of oxygen. The method demonstrated a limit of detection to be 0.12 µM. This colorimetric method exhibited an excellent selectivity towards CN- ions detection, over other common interference ions. Further, the proposed assay proved reliable and applicable for real water samples with acceptable recovery percentages. Moreover, to enhance the practical applicability, a smartphone-based detection platform was developed for on-site CN- ion monitoring.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144618572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon addition of water to the methanolic solution of L, enhancement of fluorescence was observed with a detection limit (LOD) of 0.1634 wt %. The enhancement of fluorescence emission is due to the formation of aggregation induced emission fluorescence enhancement (AIEE). Further, formation of AIEE was established through dynamic light scattering (DLS), scanning electron microscope (SEM) and quantum mechanical (DFT and TDDFT) analysis.

The experimental results show that the fluorescence signal of the composite is quenched in the presence of silver nanolayers. A good linear relationship between the fluorescence intensity of the probe and the O₂⁻ concentration is observed within the range of 0.2-2 µM, with a calculated detection limit (LOD) of 190 nM (LOD=[Formula: see text]). This demonstrates the probe's capability for sensitive and quantitative detection of O₂⁻ in biological systems. In addition, O-QD@Ag composite exhibits excellent biocompatibility and low toxicity, which is characterized by low toxicity in normal MCF-10 A and MDA-MB-436 cancer cells, and is suitable for selective detection of intracellular O₂⁻.
