[PMID: 37742548 DOI: 10.1016/j.foodchem.2023.137506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 09/10/2023] [Accepted: 09/14/2023] [Indexed: 09/26/2023]
Abstract
Sulfur dioxide (SO2), widely used as an antioxidant and preservative in food production, has been associated with detrimental cardiovascular and neurological effects when consumed excessively. This highlights the pressing need to develop a fast and sensitive probe capable of high-throughput screening for the quantitative determination of SO2 in food. Herein, we synthesized a new fluorescent probe, namely B3, specifically designed for high-throughput detection of SO2 in food. The vinyl chloride aldehyde within the B3 structure engages in a nucleophilic addition reaction with SO2, contributing to B3's exceptional selectivity for SO2, and fast response time within 9 s. Furthermore, by integrating B3 with a microplate reader, we effectively achieved high-throughput detection of SO2 concentration up to 45 μM within a pH range of 5.5 to 8.0 in real food samples. This accomplishment serves as a significant contribution to ensuring consumer safety and facilitating health assessments.

Abstract
Hydrazine (N2H4) produced by industries is distributed into different environments, and seriously threatens ecology and human security. Hence, it is important to develop probes that detect N2H4 in various environments. In this study, a novel N2H4 fluorescent probe was prepared based on a dibenzothiazole derivative (DBTD). The obtained DBTD probe demonstrated a strong ratio of colorimetric detection of N2H4, a rapid response, and good selectivity and sensitivity (detection limit 0.438 μM). Based on its good performance, the DBTD probe was successfully applied for the determination of trace N2H4 in water, cells, and zebrafish. In addition, the results of the fluorescence colocalization experiment demonstrated the lysosomal-targetable ability of DBTD.

Abstract
A turn-on fluorescence probe PQP-1 with a pyrroloquinoline skeleton has been designed and synthesized. Probe PQP-1 showed high sensitivity to HSO3-, low detection limit (16.83 nM), and a wide linear range (50-3000 μM). More importantly, probe PQP-1 could distinguish between HSO3- and SO32-. Furthermore, cell imaging experiments of HSO3- in HeLa cells revealed that probe PQP-1 had potential application value in biological systems.
