1In this work, a facile photoluminescence (PL) modulated nanosensor was designed for sulfite 2 detection. The nanosensor was based on the different quenching effect of Fe 3+ and Fe 2+ on the PL 3 intensity of nitrogen-doped graphene quantum dots (N-GQDs). Firstly, the PL of N-GQDs was 4quenched with the addition of Fe 3+ due to the strong selective coordination between the N-GQDs 5 and Fe 3+ . At the PL recovery step, Fe 3+ can be transformed to Fe 2+ with the addition of sulfite. 6Because Fe 2+ had no apparent quenching effect on N-GQDs, the N-GQDs PL signal can be 7 enhanced largely. Under the optimal condition, the PL of N-GQDs displayed a good liner 8 relationship versus the concentration of sulfite in the range of 4.0-200.0 µM. The limit of detection 9 was 1.43 µM. This was the first time that sulfite detection had been based on the PL modulation of 10 N-GQDs. The proposed method was facile, sensitive and fast for sulfite detection with simple 11 operation and materials. And sulfite in real water samples has been successfully detected with 12 satisfactory results. Furthermore, the sensing application range of N-GQDs has been extended 13 based on this novel concept. 14 15

“…The presence of sulfite anions monomerized the fluorophore, with the monomer being blue. This allowed for the quantification of sulfite with a LOD of 3.19 µM [141]. A similar concept, albeit in reverse, was also used by the same authors to quantify sulfite.…”

Beer is one of the most consumed beverages in the world. Advances in instrumental techniques have allowed the analysis and characterization of a large number of beers. However, review studies that outline the methodologies used in beer characterization are scarce. Herein, a systematic review investigating the molecular targets and sensometric techniques in beer characterization was performed following the PRISMA protocol. The study reviewed 270 articles related to beer analysis in order to provide a comprehensive summary of the recent advances in beer analysis, including methods using sensors and sensing systems. The results revealed the use of various techniques that include several technologies, such as nanotechnology and electronics, often combined with scientific data analysis tools. To our knowledge, this study is the first of its kind and provides the reader with a faithful overview of what has been done in the sensor field regarding beer characterization.

“…Therefore, sensing sulphur-containing anions is still desired to avoid its negative effect on humans. Currently, several AIE-based fluorescent sensors for the detection of SO 3 2− , HSO 3 − , and HSO 4 − have been developed (Jiang et al, 2019;Xie, Jiang, Zeng, Yu, & Wu, 2014;Xie, Zeng, Yu, & Wu, 2013;Yang et al, 2016). For example, Lin, Su et al (2019) in food (Figure 11b).…”

As a global public health problem, food safety has attracted increasing concern.To minimize the risk exposure of food to harmful ingredients, food quality and safety inspection that covers the whole process of "from farm to fork" is much desired. Fluorescent sensing is a promising and powerful screening tool for sensing hazardous substances in food and thus plays a crucial role in promoting food safety assurance. However, traditional fluorphores generally suffer the problem of aggregation-caused quenching (ACQ) effect, which limit their application in food quality and safety inspection. In this regard, luminogens with aggregationinduced emission property (AIEgens) showed large potential in food analysis since AIEgens effectively surmount the ACQ effect with much better detection sensitivity, accuracy, and robustness. In this contribution, we review the latest developments of food safety monitoring by AIEgens, which will focus on the molecular design of AIEgens and their sensing principles. Several examples of AIE-based sensing applications for screening food contaminations are highlighted, and future perspectives and challenges in this emerging field are tentatively elaborated. We hope this review can motivate new research ideas and interest to aid food safety and quality control, and facilitate more collaborative endeavors to advance the state-of-the-art sensing developments and reduce actual translational gap between laboratory research and industrial production.
