Magnetic beads harboring peptides (peptide beads) showed a higher BPA removal capacity (8.6 mg\/g) than that of bare beads without peptides (2.0 mg\/g). The BPA adsorption capacity of peptide beads increased with the number of peptides fused onto the beads, where monomeric, dimeric, or trimeric repeats of a BPA-binding peptide were fused to magnetic beads. The BPA-adsorbing beads were regenerated using a methanol\u2013acetic acid mixture, and after six regeneration cycles, the adsorption capacity remained above 87% of its initial capacity. The selective removal of BPA was confirmed in the presence of BPA analogs with high structural similarity (bisphenol F and bisphenol S) or in synthetic wastewater. The present work is a pioneering study that investigates the selective affinity of peptides to remove specific organics with high selectivity from complex environmental matrices.<\/jats:p>","DOI":"10.3390\/ma17071651","type":"journal-article","created":{"date-parts":[[2024,4,3]],"date-time":"2024-04-03T11:01:41Z","timestamp":1712142101000},"page":"1651","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Selective Removal of Bisphenol A Using a Magnetic Adsorbent Fused with Bisphenol A-Binding Peptides"],"prefix":"10.3390","volume":"17","author":[{"given":"Yue","family":"Xu","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, University of Ulsan, Ulsan 44610, Republic of Korea"},{"name":"School of Chemistry and Chemical Engineering, Shanghai University of Engineering Science, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yujie","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, University of Ulsan, Ulsan 44610, Republic of Korea"},{"name":"School of Chemistry and Chemical Engineering, Shanghai University of Engineering Science, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bharat","family":"Bhargawa","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, University of Ulsan, Ulsan 44610, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soon Ho","family":"Hong","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, University of Ulsan, Ulsan 44610, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3013-5312","authenticated-orcid":false,"given":"Ik-Keun","family":"Yoo","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, University of Ulsan, Ulsan 44610, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5711","DOI":"10.1007\/s11356-014-3974-5","article-title":"Bisphenol A, nonylphenols, benzophenones, and benzotriazoles in soils, groundwater, surface water, sediments, and food: A review","volume":"22","author":"Careghini","year":"2015","journal-title":"Environ.
