Europium(III)-driven red photoluminescent sensor for ultra-sensitive and reliable assay of sildenafil citrate in pure form, pharmaceutical formulations and Bio-fluids
{{output}}
Lanthanide complexes, particularly Eu3+ β-diketonates, offer narrow-band, long-lived red emission ideally suited to sensitive fluorescence assays in complex media. The Eu(TTA)3(H2O)2 chelate combines efficient near-UV excitation, robust emission and labile co... ...
