The actual milk samples were detected by the addition method and compared with the high\u2010performance liquid phase method; no significant difference was found in the detection results. The working electrode prepared by cross\u2010linking method not only extends the service life of the sensor, but also improves the sensitivity and reproducibility of the sensor. It can also be used to detect the Pen G residue in the actual milk samples repeatedly.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Practical Application<\/jats:title>\n                    <jats:p>In this study, an electrochemical sensor for the rapid detection of penicillin sodium in milk was prepared, which has good sensitivity and fast detection speed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/1750-3841.15841","type":"journal-article","created":{"date-parts":[[2021,7,20]],"date-time":"2021-07-20T12:25:01Z","timestamp":1626783901000},"page":"3505-3516","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Penicillin biosensor based on rhombus\u2010shaped porous carbon\/hematoxylin\/penicillinase"],"prefix":"10.1111","volume":"86","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6696-9303","authenticated-orcid":false,"given":"Hongsu","family":"Wang","sequence":"first","affiliation":[{"name":"College of Food Science and Engineering Jilin University  Changchun People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering Jilin University  Changchun People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Xiu","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering Jilin University  Changchun People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaoqi","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering Jilin University  Changchun People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Song","family":"Wang","sequence":"additional","affiliation":[{"name":"Laboratory of Theoretical and Computational Chemistry Institute of Theoretical Chemistry Jilin University  Changchun People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaodi","family":"Niu","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering Jilin University  Changchun People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,7,20]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1149\/1945\u20107111\/ab9d94"},{"key":"e_1_2_8_3_1","first-page":"293\u2013307)","volume-title":"Bio\u2010farms for nutraceuticals: Functional food and safety control by biosensors","author":"Barthelmebs L.","year":"2010"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja304398b"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010020\u201070263\u2010z"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13738\u2010020\u201002047\u20101"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/jaoac\/88.2.447"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2019.120641"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelechem.2020.114557"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/jf072550n"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/bios8020053"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bios.2008.08.024"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1093\/jaoac\/88.3.679"},{"issue":"1","key":"e_1_2_8_14_1","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1016\/S1452-3981(23)04994-5","article-title":"Simultaneous determination of hydroxylamine, phenol and sulfite in water and waste water samples using a voltammetric nanosensor","volume":"10","author":"Gupta V.
