Resumo
Low-density lipoprotein (LDL) is known as ‘bad’ cholesterol. If too much LDL circulates in the blood it can be retained
in the walls of the arteries, causing atherosclerosis. In this paper we showed an alternative method to quantify LDL using the
europium tetracycline (EuTc) indicator. The optical properties of the EuTc complex were investigated in aqueous solutions
containing LDL. An enhancement was observed of the europium luminescence in the solutions with LDL compared those
without the lipoprotein. A method to quantify the amount of LDL in a sample, based on EuTc enhanced luminescence, is proposed.
The enhancement mechanism is also discussed.
