Magnetic and golden yogurts. Food as a Potential Nanomedicine Carrier Garcés Robles, Víctor Jesús González Garnica, Ana Isabel Sabio Rodríguez, Laura Sánchez-Arévalo, Carmen María Gálvez Rodríguez, Natividad Domínguez Vera, José Manuel Yogurt Gold nanoparticles Functional food Magnetic nanoparticles This research was funded by the Spanish Ministry of Science, Innovation, and Universities (MICINN) (project FEDER CTQ2015-64538-R).

Supplementary Materials: The following are available online at http://www.mdpi.com/1996-1944/13/2/481/s1 Yogurt is one of the most emblematic and popular fermented foods. It is produced by the fermentation of milk lactose by bacteria such as Streptococcus thermophilus and Lactobacillus acidophilus. Magnetic (MNPs) and gold nanoparticles (AuNPs) were incorporated into the exopolysaccharides (EPSs) of these bacteria. The functionalized bacteria were characterized by UV-vis spectroscopy and transmission electron microscopy. A large number of MNPs and AuNPs were bound to the bacterial EPS. Interestingly, the nanoparticles’ (NPs) presence did not a ect the bacteria’s capacity to ferment milk and to produce magnetic and golden yogurts. Magnetic and golden yogurts represent the perfect combination of emblematic food and nanoparticles and have a range of potential biomedical applications: use in iron-deficiency anemia, diagnosis and hyperthermia treatment of appropriate digestive diseases, and interest in glamour cuisine. 2025-05-15T06:36:01Z 2025-05-15T06:36:01Z 2020-01-19 journal article Garcés, V., González, A., Sabio, L., Sánchez-Arévalo, C.
