Tb-atorvastatin doped in poly(ethylene glycol) optical biosensor for selective determination of progesterone and testosterone in serum samples.

An innovative, simple and cost effective Tb-atorvastatin photo probe was designed and used as a core for a spectrofluorometric approach to sensitively determine two vital biological compounds in serum samples. Tb-atorvastatin complex displays a characteristic electrical band with at 545 nm with significant luminescence intensity, which is quenched in the presence of progesterone and testosterone at two variant sets of pH; 6.2 and 7.

New Tb-simvastatin optical biosensor for sensitive determination of folic acid, progesterone, testosterone and vitamin D in biological fluids.

An innovative, simple and cost effective Tb-simvastatin photo probe was designed and used as a core for a spectrofluorometric approach to sensitively determine four vital biological compounds in different matrices. A Tb-simvastatin complex displays a characteristic electrical band with at 545 nm with significant luminescence intensity, which is quenched in the presence of folic acid, progesterone, testosterone and vitamin D at four variant sets of pH: 5.0, 6.
