Detection of DNA chemical methylation damage using lateral flow strips based on DNA repair enzymes
YOU Hongting;SHI Sanjun;HUANG Rongfu;FAN Ziyan;CHE Jiangtao;WANG Lei;A sensor that can rapidly and quantitatively detect DNA chemical methylation damage without labels was proposed by utilizing DNA repair enzymes for recognition and lateral flow strips(LFS). This sensing strategy introduced alkyladenine DNA glycosylase(hAAG) and human apurinic/apyrimidinic endonuclease 1(APE 1), which could convert the damaged DNA into broken strands. Then, the gold nanoparticle(AuNPs) complexes bound to DNA could be captured on the test line(T line), displaying an obvious red color. In addition, the average gray value of the optical density in the T line area was analyzed using a mobile phone camera and Image J software to quantify the methylation damage to DNA caused by methyl methanesulfonate(MMS). Under the optimized experimental conditions, the prepared biosensor can detect the methylation damage caused by MMS at a minimum concentration of 1 mmol/L. This biosensor has realized the detection of DNA methylation damage, exhibiting substantial application potential in the evaluation of the genotoxicity induced by chemical pollutants.

Determination of aluminum ion by hydrogen peroxide-mediated polydopamine fluorescent probe
WANG Dongxin;YU Liping;QIAO Zengjie;LIU Wen;This study developed a rapid detection method for aluminum ion (Al3+) based on water-soluble fluorescent poly(dopamine) (FPDA). At room temperature， water-soluble FPDA was synthesized via a one-pot method. Leveraging its fluorescence enhancement properties upon Al3+ binding， a novel fluorescent sensing platform for rapid Al3+ detection was established. O-Phenylenediamine was employed to mask interference from Fe2+/Fe3+ in samples， enhancing the method's selectivity. Results demonstrated a good linear relationship between Al3+ concentration (0.2–40.0 μmol/L) and FPDA fluorescence intensity. The detection limit reached 0.12 μmol/L， with spiked recovery rates ranging from 97.4% to 103.0% and relative standard deviations below 1%. This method is suitable for rapid quantitative detection of Al3+ in water bodies.

Simultaneous rapid detection of four major phenylethanoid glycosides in Cistanche based on digital image processing of thin-layer chromatography
BAI Yawen;JI Shuyi;LI Qinqin;Nurmammat·Kader;JI Kunfeng;LI Hai;SHEN Jing;YAO Jun;A digital image-based thin-layer chromatography (TLC) analysis method was developed for the rapid， simple， and low-cost detection of four major phenylethanolic glycosides in Cistanche. The four target compounds were extracted using 50% methanol. A mobile phase consisting of methanol chloroform， glacial， acetic acid， and water (3.5:1.5:1:7) was used for TLC development， and spot images were captured under 365 nm ultraviolet light. The spots were integrated and analyzed using ImageJ software， enabling rapid quantitative analysis based on grayscale values. The linear correlation coefficients (r) obtained by this method were 0.9974， 0.9931， 0.9923 and 0.9890， respectively. The spiked recovery rates for echinacoside， tubuloside A， acteoside， and isoacteoside in Cistanche were 87.1% -96.5%， 88.4% -109.7%， 94.1% -105.1%， and 97.0% -115.1%， respectively. The quantitative results of the established method were basically consistent with those obtained by high-performance liquid chromatography (HPLC). This digital image processing method based on TLC provides a fast and accurate method for determining the contents of four phenylethanolic glycosides in Cistanche.

Simultaneous determination of five kinds of cyanotoxins in drinking water by direct injection-hydrophilic interaction- liquid chromatography-tandem mass spectrometer
QIU Fengmei;FANG Li;A method for quantitative analysis of five kinds of cyanotoxins (Microcystin-LR (MC-LR)， Cylindrospermopsin (CYN)， Nodularin (NOD)， Anatoxin-a (ATX-a)， and Lyngbya wollei toxin (LWTX-1)) in drinking water was established by utilizing liquid chromatography coupled with triple quadrupole mass spectrometry. The water sample was collected and filtered through a 0.22 μm polyethersulfone filter membrane， the targets were separated on an Acquity UPLC BEH Amide column with the mobile phases of 5 mmol/L ammonium formate aqueous solution with 0.1% formic acid and acetonitrile， and determined in selected reaction monitoring (SRM) mode via positive electrospray ionization. Quantitative analysis was performed using the external standard method. The five cyanotoxins showed good linearity in the concentration range of 0.2-10.0 μg/L， with the correlation coefficients higher than 0.998. The limits of detection and limits of quantitation of five cyanotoxins based on 3 and 10 signal-to-noise (S/N) ratios were 0.03-0.06 μg/L and 0.1-0.2 μg/L， respectively. The inter- and intra-day recoveries of five cyanotoxins were 83.6%-107.8% and 85.6%-107.8%， respectively， as the samples were spiked at four levels of 0.2， 0.5， 2， and 5 μg/L. Both the inter-day and intra-day relative standard deviations (RSDs ) were lower than 13%. The method can satisfy the requirements of emergency testing and routine monitoring of cyanotoxins in source water and drinking water.

Research progress on the application of gas chromatography-ion mobility spectrometry technology in flavor evaluation of condiments
HOU Meiling;BAI Yamin;Gas chromatography-ion mobility spectrometry (GC-IMS) has demonstrated significant value in condiment flavor analysis due to its advantages of high sensitivity， rapid analysis， and no requirement for complex sample preparation. This review systematically summarizes the innovative applications of GC-IMS in condiment flavor research， with a particular focus on its breakthrough progress in elucidating the multidimensional flavor formation mechanism spanning from raw materials - processing to final flavor characteristics. Studies have shown that GC-IMS not only enables dynamic monitoring of fermentation processes such as soy sauce and vinegar but also reveals the formation mechanisms of key flavor compounds through multi-technology integration. In the analysis of spices and compound condiments， this technology has successfully achieved the quantification of spiciness levels， resolution of flavor contributions， and quality control of products. Furthermore， GC-IMS has provided a scientific basis for process optimization and origin identification in aquatic condiment research. Although challenges remain in database completeness and quantitative analysis， GC-IMS is expected to play a more important role in food flavoromics and intelligent quality control with the development of instrument miniaturization and artificial intelligence technologies. This review provides new research perspectives for understanding the flavor formation mechanisms of condiments and offers important guidance for advancing the development of food flavor science.
