This study reports a new chemical sensor based on ion-imprinted polymer matrix using copper nanoparticles-polyaniline nanocomposite (IIP-Cu-NPs/PANI). was prepared by electropolymerization aniline as functional monomer and nitrate template onto the nanoparticles-modified glassy carbon (GC) electrode surface. Both (IIP) nonimprinted (NIP) electrochemical surfaces were evaluated UV-Visible spectrometry scanning electron microscopy (SEM). The analysis made via cyclic voltammetry (CV), linear...
Abstract An electrochemical sensor for amoxicillin (AMX) detection based on reduced graphene oxide (RGO), molecular imprinted overoxidized polypyrrole (MIOPPy) modified with gold nanoparticles (AuNPs) is described in this work. The behavior of the and non‐imprinted polymer (NIP) was carried out by cyclic voltammetry (CV) impedance spectroscopy (IS). structure morphology prepared MIP were characterized scanning electron microscopy (SEM), UV‐Visible, Fourier transform infrared (FTIR) its...
To protect consumers from risks related to overexposure sulfadiazine, total residues of this antibacterial agent in animal-origin foodstuffs not exceed international regulations. end, a new electrochemical sensor based on molecularly imprinted polymer nanocomposite using overoxidized polypyrrole and copper nanoparticles for the detection sulfadiazine is elaborated. After optimization preparation sensors, their differential pulse voltammetric signal exhibits an excellent stability...
Abstract Heavy metal ion pollution poses a significant threat to environmental and human health. We developed highly selective sensitive electrochemical sensor for mercury(II) detection, utilizing synthesized nickel(II) complex, [(5,10,15,20-tetrakis(p-bromophenyl)porphyrinato] Nickel(II) [Ni(TBrPP)]. The structural integrity, composition, physicochemical properties of [Ni(TBrPP)] were characterized using comprehensive set analytical techniques, including Proton nuclear magnetic resonance,...
Abstract This work was designed to develop an electrochemical sensor based on molecular imprinted polyaniline membranes onto reduced graphene oxide (RGO) and gold nanoparticles (AuNPs) modified glassy carbon (GC) electrode for dapsone (DDS) determination. The prepared RGO/AuNPs/PANI‐MIPs nanocomposite characterized by Ultra‐Violet‐Visible (UV‐Vis), Fourier transform infrared spectroscopy (FT‐IR) scanning electronic microscopy (SEM) images. feature of the evaluated cyclic voltammetry (CV),...
