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.
