Resumo
We report here the observation, for the first time,
of the enhancement of Europium-Tetracycline complex
emission in cholesterol solutions. This enhancement was
initially observed with the addition of the enzyme cholesterol
oxidase, which produces H2O2, the agent driver of the
Europium tetracycline complex, to the solution. However, it
was found that the enzyme is not needed to enhance the
luminescence. A calibration curve was determined, resulting
in a simple method to measure the cholesterol quantity in a
solution. This method shows that the complex can be used as
a sensor to determine cholesterol in biological systems.
