In the present work, a laser-induced carbon (LIC) electrode is proposed for 4-Aminophenol (4-AP) electrochemical sensors. The electrode is patterned on a commercial low-cost polyimide (Kapton) sheet and functionalized with a multi-walled carbon nanotubes polyaniline (MWCNT-PANI) composite, realized by an in-situ-polymerization in an acidic medium. The LIC electrode modified with MWCNT-PAPNI nanocomposite was investigated by SEM, AFM, and electrochemically in the presence of ferri-ferrocyanide [Fe(CN)6]3\u2212\/4\u2212 by cyclic voltammetry and impedance spectroscopy. The results show a significant improvement of the electron transfer rate after the electrode functionalization in the presence of the redox mediators [Fe(CN)6]3\u2212\/4\u2212, related directly to the active surface, which itself increased by about 18.13% compared with the bare LIG. The novel electrode shows a good reproducibility and a stability for 20 cycles and more. It has a significantly enhanced electro-catalytic activity towards electrooxidation reaction of 4-AP inferring positive synergistic effects between carbon nanotubes and polyaniline PANI. The presented electrode combination LIC\/MWCNT-PANI exhibits a detection limit of 0.006 \u03bcM for the determination of 4-AP at concentrations ranging from 0.1 \u03bcM to 55 \u03bcM and was successfully applied for the monitoring in real samples with good recoveries.<\/jats:p>","DOI":"10.3390\/s22030833","type":"journal-article","created":{"date-parts":[[2022,1,23]],"date-time":"2022-01-23T20:36:27Z","timestamp":1642970187000},"page":"833","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Development of an Efficient Voltammetric Sensor for the Monitoring of 4-Aminophenol Based on Flexible Laser Induced Graphene Electrodes Modified with MWCNT-PANI"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8936-9108","authenticated-orcid":false,"given":"Salem","family":"Nasraoui","sequence":"first","affiliation":[{"name":"Professorship of Measurement and Sensor Technology, Chemnitz University of Technology, 09111 Chemnitz, Germany"},{"name":"Centre for Research on Microelectronics and Nanotechnology of Sousse, Tunisia and NANOMISENE Lab, LR16CRMN01, University of Sousse Sahloul, Sousse 4003, Tunisia"}]},{"given":"Sami","family":"Ameur","sequence":"additional","affiliation":[{"name":"Centre for Research on Microelectronics and Nanotechnology of Sousse, Tunisia and NANOMISENE Lab, LR16CRMN01, University of Sousse Sahloul, Sousse 4003, Tunisia"},{"name":"Higher Agronomic Institute of Chott-Mariem, University of Sousse, Sousse 4034, Tunisia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0952-3134","authenticated-orcid":false,"given":"Ammar","family":"Al-Hamry","sequence":"additional","affiliation":[{"name":"Professorship of Measurement and Sensor Technology, Chemnitz University of Technology, 09111 Chemnitz, Germany"}]},{"given":"Mounir","family":"Ben Ali","sequence":"additional","affiliation":[{"name":"Centre for Research on Microelectronics and Nanotechnology of Sousse, Tunisia and NANOMISENE Lab, LR16CRMN01, University of Sousse Sahloul, Sousse 4003, Tunisia"},{"name":"Higher Institute of Applied Sciences and Technology of Sousse, University of Sousse, Sousse 4003, Tunisia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7166-1266","authenticated-orcid":false,"given":"Olfa","family":"Kanoun","sequence":"additional","affiliation":[{"name":"Professorship of Measurement and Sensor Technology, Chemnitz University of Technology, 09111 Chemnitz, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Della Pelle, F., and Compagnone, D.
