In this study, hydrophobic octyl (C8) functionalized Fe3O4 magnetic nanoparticles (MNPs) stabilized by SiOH groups (Fe3O4@SiO2@C8) are used as magnetic nano¨Csorbents for the extraction of cardiovascular drugs from human plasma prior to their determination by high performance liquid chromatography¨Cphotodiode array detection %K High¨Cperformance liquid chromatography %K Magnetic solid phase extraction %K Plasma %K Atorvastatin %K Losartan %K Valsartan %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6468226/
