Hence, there is a pressing need to realize the simple and precise detection of Gly to ensure human health and environmental safety. Although various nanozyme-based detection methods have been developed for Gly, they frequently require additional enzymes and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>). H<sub>2</sub>O<sub>2</sub> not only exhibits certain toxicity but is also prone to decomposition, resulting in poor accuracy and reproducibility. In this study, we report the synthesis of nanoscale copper-based metal-organic framework (Cu-MOF) through a facile ultrasound method, and the resulting Cu-MOF demonstrate excellent laccase-mimicking activity. Our Cu-MOF nanozyme can catalyze the conversion of substrates into chromogenic products without the need for H<sub>2</sub>O<sub>2</sub>, offering a simple and mild operational approach. The presence of Gly significantly inhibits the catalytic activity of the Cu-MOF, hindering the chromogenic reaction between 2,4-dichlorophenol (2,4-DP) and 4-aminoantipyrine (4-AP). We propose a detection method for Gly that is repeatable, reliable, highly selective, and cost-effective, eliminating the need for additional H<sub>2</sub>O<sub>2</sub>, or bioenzymes.

Therefore, achieving high sensitivity and low limit of detection (LOD) for specific detection of HCHO is critically important. In this work, a HCHO electrochemical sensor was prepared using a two-step drop-coating method on a flexible planar screen-printed electrode, with 60 % Pt/C-Nafion catalyst as the sensing layer and Nafion as the solid-state electrolyte. At a working potential of 0.5 V, high sensitivity (0.197 μA/ppm), a wide linear response range (HCHO concentration from 500 ppb to 100 ppm) and a low LOD (2.5 ppb) have been achieved for HCHO detection at room temperature. The sensor also exhibits excellent selectivity, consistency and long-term stability (>15 days). Through ultra-low concentration sensing tests of 50-400 ppb HCHO using a fluorine membrane gas bag, the sensor demonstrates good linearity with a sensitivity of 0.8 nA/ppb, which can effectively distinguish between exhaled breath from healthy individuals and simulated lung cancer patients. The appropriate selection of working potential, efficient construction of three-phase boundary (TPB) and excellent electrocatalytic performance of the Pt/C catalyst enable the realization of high-performance HCHO detection. Additionally, the sensor preparation method is simple and cost-effective. Therefore, the proposed Nafion-based HCHO electrochemical sensor is expected to provide a promising sensing platform for lung cancer screening in clinical diagnosis and indoor HCHO concentration monitoring.</p>","PeriodicalId":435,"journal":{"name":"Talanta","volume":"293 ","pages":"128148"},"PeriodicalIF":5.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
