This comprehensive review delves into the latest advancements in electrochemical methods for detecting formaldehyde, a compound of growing concern due to its widespread use and potential health hazards. This review underscores the inherent advantages of electrochemical techniques, such as high sensitivity, selectivity, and capability for real-time analysis, making them highly effective for formaldehyde monitoring. We explore the fundamental principles, mechanisms, and diverse methodologies employed in electrochemical formaldehyde detection, highlighting the role of innovative sensing materials and electrodes. Special attention is given to recent developments in nanotechnology and sensor design, which significantly enhance the sensitivity and selectivity of these detection systems. Moreover, this review identifies current challenges and discusses future research directions. Our aim is to encourage ongoing research and innovation in this field, ultimately leading to the development of advanced, practical solutions for formaldehyde detection in various environmental and biological contexts.<\/jats:p>","DOI":"10.3390\/molecules29020327","type":"journal-article","created":{"date-parts":[[2024,1,9]],"date-time":"2024-01-09T04:38:51Z","timestamp":1704775131000},"page":"327","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["Recent Advances in Electrochemical Sensors for Formaldehyde"],"prefix":"10.3390","volume":"29","author":[{"given":"Yufei","family":"Yang","sequence":"first","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Shangqiu Normal University, Shangqiu 476000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1038-0089","authenticated-orcid":false,"given":"Yuanqiang","family":"Hao","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Shangqiu Normal University, Shangqiu 476000, China"},{"name":"Key Laboratory of Theoretical Organic Chemistry and Functional Molecule of Ministry of Education, School of Chemistry and Chemical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijie","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Shangqiu Normal University, Shangqiu 476000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanjian","family":"Luo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Theoretical Organic Chemistry and Functional Molecule of Ministry of Education, School of Chemistry and Chemical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5509-2684","authenticated-orcid":false,"given":"Shu","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Theoretical Organic Chemistry and Functional Molecule of Ministry of Education, School of Chemistry and Chemical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maotian","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Shangqiu Normal University, Shangqiu 476000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3426-2653","authenticated-orcid":false,"given":"Wansong","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Central South University, Changsha 410017, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e202300174","DOI":"10.1002\/cssc.202300174","article-title":"Advances of Modified Lignin as Substitute to Develop Lignin-Based Phenol-Formaldehyde Resin Adhesives","volume":"16","author":"Peng","year":"2023","journal-title":"ChemSusChem"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Hor\u00e1kov\u00e1, P., and Ko\u010d\u00ed, K.
