Abstract:

Cholesterol is a lipid molecule in protein and cell membrane and precursor of bile acids, steroids hormones and vitamin D. Higher level of cholesterol, especially low-density lipoprotein (LDL), becomes a cause of cardiovascular disease (CVD). Adsorbent of LDL from human blood plasma plays crucial role for the treatment of hyperlipidemia. Therefore, a suitable adsorbent material for efficient and selective adsorption of low-density lipoprotein is beneficial. In this work, amino acids assisted iron oxide (Fe3O4) was synthesized by hydrothermal method. The morphology, size, crystallinity, and chemical attachment of Fe3O4 nanoparticles are characterized by SEM, FESEM/EDS, HRTEM, XRD, XPS, FTIR, and Raman spectroscopy. The lysine-assisted Fe3O4 (Fe3O4-L) nanoparticles have successfully absorbed LDL in plasma, which shows a higher selectivity, as well as attain outstanding adsorption capacity as high as 30.19% within 1 h.
