The detection mechanism is based on the color change of the probe upon the aggregation of the nanoparticles induced by the polymerization of the resorcinol moieties in the presence of formaldehyde. A limit of detection of 0.5 ppm in solution has been determined. The probe can be deployed for the detection of formaldehyde emissions from composite wood boards.<\/jats:p>","DOI":"10.3390\/nano9020302","type":"journal-article","created":{"date-parts":[[2019,2,22]],"date-time":"2019-02-22T11:26:14Z","timestamp":1550834774000},"page":"302","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Resorcinol Functionalized Gold Nanoparticles for Formaldehyde Colorimetric Detection"],"prefix":"10.3390","volume":"9","author":[{"given":"Carlos","family":"Mart\u00ednez-Aquino","sequence":"first","affiliation":[{"name":"Instituto Interuniversitario de Investigaci\u00f3n de Reconocimiento Molecular y Desarrollo Tecnol\u00f3gico (IDM), Universitat Polit\u00e9cnica de Val\u00e8ncia, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9640-1148","authenticated-orcid":false,"given":"Ana M.","family":"Costero","sequence":"additional","affiliation":[{"name":"Instituto Interuniversitario de Investigaci\u00f3n de Reconocimiento Molecular y Desarrollo Tecnol\u00f3gico (IDM), Universitat Polit\u00e9cnica de Val\u00e8ncia, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"},{"name":"Departamento de Qu\u00edmica Org\u00e1nica, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"},{"name":"CIBER de Bioingenier\u00eda, Biomateriales y Nanomedicina (CIBER-BBN), 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2818-1320","authenticated-orcid":false,"given":"Salvador","family":"Gil","sequence":"additional","affiliation":[{"name":"Instituto Interuniversitario de Investigaci\u00f3n de Reconocimiento Molecular y Desarrollo Tecnol\u00f3gico (IDM), Universitat Polit\u00e9cnica de Val\u00e8ncia, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"},{"name":"Departamento de Qu\u00edmica Org\u00e1nica, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"},{"name":"CIBER de Bioingenier\u00eda, Biomateriales y Nanomedicina (CIBER-BBN), 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8496-6448","authenticated-orcid":false,"given":"Pablo","family":"Gavi\u00f1a","sequence":"additional","affiliation":[{"name":"Instituto Interuniversitario de Investigaci\u00f3n de Reconocimiento Molecular y Desarrollo Tecnol\u00f3gico (IDM), Universitat Polit\u00e9cnica de Val\u00e8ncia, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"},{"name":"Departamento de Qu\u00edmica Org\u00e1nica, Universitat de Val\u00e8ncia, Doctor Moliner 50, Burjassot, 46100 Valencia, Spain"},{"name":"CIBER de Bioingenier\u00eda, Biomateriales y Nanomedicina (CIBER-BBN), 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3320","DOI":"10.1002\/anie.201205984","article-title":"Formaldehyde in the ambient atmosphere: from an indoor pollutant to an outdoor pollutant?","volume":"52","author":"Salthammer","year":"2013","journal-title":"Angew.
