Polydatin was selected as a template polyphenol due to its relatively high size and amphiphilic character. Different MIPs were synthesized to explore preferential interactions between the functional monomers and the template molecule. The effect of solvent polarity on the molecular imprinting efficiency, namely owing to hydrophobic interactions, was also assessed. Precipitation and suspension polymerization were examined as a possible way to change MIPs morphology and performance. Solid phase extraction and batch\/continuous sorption processes were used to evaluate the polyphenols uptake\/release in individual\/competitive assays. Among the prepared MIPs, a suspension polymerization synthesized material, with 4-vinylpyridine as the functional monomer and water\/methanol as solvent, showed a superior performance. The underlying cause of such a significant outcome is the likely surface imprinting process caused by the amphiphilic properties of polydatin. The uptake and subsequent selective release of polyphenols present in natural extracts was successfully demonstrated, considering a red wine solution as a case study. However, hydrophilic\/hydrophobic interactions are inevitable (especially with complex natural extracts) and the tuning of the polarity of the solvents is an important issue for the isolation of the different polyphenols.<\/jats:p>","DOI":"10.3390\/pr5040072","type":"journal-article","created":{"date-parts":[[2017,11,14]],"date-time":"2017-11-14T10:58:32Z","timestamp":1510657112000},"page":"72","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Development of Molecularly Imprinted Polymers to Target Polyphenols Present in Plant Extracts"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3396-3615","authenticated-orcid":false,"given":"Catarina","family":"Gomes","sequence":"first","affiliation":[{"name":"LSRE-Instituto Polit\u00e9cnico de Bragan\u00e7a, Quinta de Santa Apol\u00f3nia, 5300 Bragan\u00e7a, Portugal"}]},{"given":"Gayane","family":"Sadoyan","sequence":"additional","affiliation":[{"name":"LSRE-Instituto Polit\u00e9cnico de Bragan\u00e7a, Quinta de Santa Apol\u00f3nia, 5300 Bragan\u00e7a, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7369-382X","authenticated-orcid":false,"given":"Rolando","family":"Dias","sequence":"additional","affiliation":[{"name":"LSRE-Instituto Polit\u00e9cnico de Bragan\u00e7a, Quinta de Santa Apol\u00f3nia, 5300 Bragan\u00e7a, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7807-4275","authenticated-orcid":false,"given":"M\u00e1rio","family":"Costa","sequence":"additional","affiliation":[{"name":"LSRE-Faculdade de Engenharia da Universidade do Porto, Rua Roberto Frias s\/n, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2017,11,14]]},"reference":[{"key":"ref_1","unstructured":"Watson, R.
