Synthesis and Introducing Au-Cu Alloy Nanoparticles/Porous Silicon as a Novel Modifier of Screen Printed Carbon Electrode in Simultaneous Electrocatalytic Detection of Codeine and Acetaminophen
Abstract:In the present study, a bimetallic nanostructure of gold-copper (Au-CuNPs) was decorated on the surface of porous silicon (PSi) using an easy galvanic replacement reaction between metal ions and PSi in the presence of 0.1 M hydrofluoric acid solution. The morphology and structures of the Au-CuNPs@PSi nanocomposite were characterized using X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) energy-… Show more
“…The sensor was able to detect codeine in the range 0.06 mM-0.6 mM with an LOD of 0.35 mM. 46 It can be seen that a majority of the existing reports deal with electrochemical sensors based on carbon-based nanostructures and their composites. In addition to this very few reports deal with commercially deployable systems for the detection of opioids in surgical scenarios.…”
