Most of them were caused by pathogens like\n Campylobacter<\/jats:italic>\n spp.,\n Salmonella enterica<\/jats:italic>\n ,\n Escherichia coli<\/jats:italic>\n , and\n Listeria monocytogenes<\/jats:italic>\n . Due to the short shelf life of fresh meat and dairy products, a rapid detection of pathogens in contaminated food products is essential. Since reference methods for microbial food analysis require time-consuming nonselective and selective culturing procedures, the need for more efficient approaches is given. In this study, we employ superparamagnetic iron oxide nanoparticles (SPIONs) functionalized with the peptide KRQGRVEVLYRASWGTV derived from the salivary protein GP-340, to successfully remove different species of food-related microorganisms (\n Pseudomonas paracarnis<\/jats:italic>\n ,\n Campylobacter jejuni<\/jats:italic>\n ,\n Escherichia coli<\/jats:italic>\n ,\n Enterococcus faecalis<\/jats:italic>\n ,\n Salmonella enterica<\/jats:italic>\n , and\n Listeria monocytogenes<\/jats:italic>\n ) from pure media and homogenates derived from retail meat products. We discovered differences in extraction efficiencies from pure culture ranging from 18% (\n C. jejuni<\/jats:italic>\n ) to complete extraction (\n E. faecalis<\/jats:italic>\n ,\n L. monocytogenes<\/jats:italic>\n and\n P. paracarnis<\/jats:italic>\n ) depending on the organism. It was also shown that\n L. monocytogenes<\/jats:italic>\n could successfully be removed from co-culture with a high surplus of non-pathogenic\n P. paracarnis<\/jats:italic>\n , and also from food matrices.\n <\/jats:p>\n <\/jats:sec>\n \n Key points<\/jats:title>\n \n \u2022\n SPION<\/jats:italic>\n \n Cit<\/jats:italic>\n <\/jats:sup>\n can be functionalized with a GP-340 derived peptide (SPION<\/jats:italic>\n \n Pep<\/jats:italic>\n <\/jats:sup>\n )<\/jats:italic>\n <\/jats:p>\n \n \u2022\n SPION<\/jats:italic>\n \n Pep<\/jats:italic>\n <\/jats:sup>\n \u00a0can immobilize and remove L. monocytogenes from pure and co-culture with high surplus of non-pathogenic P. paracarnis<\/jats:italic>\n <\/jats:p>\n \n \u2022\n Removal of L. monocytogenes is also possible in complex food matrices<\/jats:italic>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1007\/s00253-026-13922-x","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T16:35:41Z","timestamp":1783355741000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Removal and analysis of foodborne-associated pathogens via peptide functionalized nanoparticles"],"prefix":"10.1007","volume":"110","author":[{"given":"Emily","family":"Hausen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Knorr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Lyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Alexiou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rainer","family":"Tietze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonja","family":"Lick","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,6]]},"reference":[{"key":"13922_CR1","doi-asserted-by":"publisher","first-page":"337","DOI":"10.1016\/j.jconrel.2016.06.017","volume":"235","author":"S Bhattacharjee","year":"2016","unstructured":"Bhattacharjee S (2016) DLS and zeta potential - what they are and what they are not?
