The date rape drug, Flunitrazepam: electroanalytical sensing using electrogenerated chemiluminescence.

Lledo-Fernandez, Carlos; Pollard, Pat; Romerosa, Antonio

Abstract

The electro-analytical sensing of Flunitrazepam is reported for the first time utilising [Ru(bpy)3]2+ as a Electrochemiluminescent reagent probe without any sample pre-treatment. The methodology is shown to be useful for quantifying low ng/mL Flunitrazepam in buffer. We have successfully demonstrated the detection of Flunitrazepam over a range of Flunitrazepam concentrations 2000 ng/mL to 50 ng/mL into a pH 4 buffer. A linear response is observed (ECL emission/mV = 0.0094x+6.3204, R2 = 0.9937 and N = 5) with a detection limit of 39 ng/mL (based on 3-sigma).
