The method is linear over the concentration range of 0.1–4.1 μg/mL for BSL and 1.0–9.0 μg/mL for AMD. The limit of detection for BSL and AMD is 0.0168 and 0.1227, and the limit of quantification is 0.0508 and 0.3717 μg/mL, respectively. This technique is effectively used to analyze the two studied drugs in their tablets with high %Recoveries of 100.09% for BSL and 99.67% for AMD and %RSD ≤ 1.54.

Fluorescence quenching of bovine serum albumin (BSA) and human serum albumin (HSA) was carried out using different concentrations of the Cys-PANI oligomers.

The quenching rate constant was found to increase with cysteine content in the polymer, showing that the loading of higher amount of Cys increased the solubility of the Cys-PANI oligomers.
