Abstract

Sulphur dioxide (SO₂) and its derivatives (SO₃²⁻/HSO₃⁻) are extensively utilized in food processing for their roles as bleaching agents, preservatives, and antimicrobials. Research has shown a strong association between high sulfur dioxide intake and various diseases. Consequently, developing rapid and accurate analytical techniques to monitor sulfur dioxide and its derivatives in food is of great value. This work designed a fluorescent probe ZR-I with a D-π-A structure using triphenylamine derivatives as electron donors. The probe ZR-I demonstrated high sensitivity and selectivity towards SO₃²⁻/HSO₃⁻, along with strong anti-interference ability. The probe has effectively quantified SO₃²⁻/HSO₃⁻ in environmental and food samples, achieving a recovery rate of 97.65–104.15 %. Additionally, in situ tracking and imaging of SO₃²⁻/HSO₃⁻ in HepG2 cells and zebrafish were successfully achieved using ZR-I, which demonstrated high contrast and high sensitivity. To enhance the convenience and practicality of detection, a smartphone-based portable sensing platform has been developed, providing an efficient and practical tool for food safety assessment.

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
