The switchable ability to control the uptake\/release of the target analyte by action of external stimulus combined with a remarkable selectivity and specificity, makes these functional materials very attractive for sample preparation purposes. In this work, the usefulness of a sample preparation tool for the selective enrichment\/pre-concentration of dimethoate from olive oil spiked samples based on \u201ctailor-made\u201d dual responsive magnetic and photonic molecularly imprinted polymers as sorbents is explored. To achieve this goal, a smart molecularly imprinted polymer (MIP) possessing magnetic and photonic responsiveness was successfully synthesized, and its physico-chemical and morphological characterization was assessed. Further, the trace analysis of dimethoate in spiked olive oil samples was validated and successfully implemented using smart-MIPs as sorbents in the sample preparation step, with high recoveries (83.5 \u00b1 0.3%) and low detection limit (0.03 \u00b5g\u00b7mL\u22121).<\/jats:p>","DOI":"10.3390\/foods9050618","type":"journal-article","created":{"date-parts":[[2020,5,12]],"date-time":"2020-05-12T10:53:55Z","timestamp":1589280835000},"page":"618","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Assessment of Dimethoate in Olive Oil Samples Using a Dual Responsive Molecularly Imprinting-Based Approach"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7000-0255","authenticated-orcid":false,"given":"Raquel","family":"Garcia","sequence":"first","affiliation":[{"name":"MED\u2014Mediterranean Institute for Agriculture, Environment and Development, Departamento de Fitotecnia, Escola de Ci\u00eancias e Tecnologia da Universidade de Lisboa, Universidade de \u00c9vora, P\u00f3lo da Mitra, Apartado 94, 7006-554 \u00c9vora, Portugal"}]},{"given":"Elisabete P.","family":"Carreiro","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica de \u00c9vora, IIFA, Universidade de \u00c9vora, Col\u00e9gio L.A.
