PhD Dissertation at University of Basrah Develops Colorimetric Biosensors for Methamphetamine Detection
A PhD dissertation at the College of Science, University of Basrah focused on the development of colorimetric biosensors based on gold and silver nanoparticles for the detection of methamphetamine (crystal meth) in biological samples.
The dissertation, presented by Jumana Mohammed Khalaf, aimed to synthesize and characterize gold and silver nanoparticles using green chemistry through N-Acetyl-L-cysteine as both a reducing and capping agent. The goal was to develop a sensitive, selective, and eco-friendly aptasensor for detecting methamphetamine in biological samples.
The research included characterization of the synthesized nanoparticles using UV–Vis, FTIR, XRD, TEM, FESEM-EDX, DLS, and zeta potential measurements. Additionally, the developed biosensors were characterized with UV–Vis and GC–MS techniques to confirm nanoparticle formation and the successful conjugation with aptamers.
