Polyaniline (PANI)-based molecularly imprinted polymers were investigated for their efficacy in sensing phenylalanine (Phe) when fabricated on both glassy carbon electrode (GCE) and indium tin oxide (ITO) sheets. This study highlights the superior performance of PANI-MIP/ITO over PANI-MIP/GCE Phe, with clear distinct redox responses. Molecular computation helps to understand interaction mechanism between PANI where molecular crowding, aggregated clusters, hydrogen bonding, π-π stacking facilitate stable interactions. We tested specificity Phe by PANI-MIP different amino acids such as cysteine, tryptophan, tyrosine well organic molecules ascorbic acid, allantoin, sucrose, urea, confirming its remarkable electrochemical efficiency. The oxidation response curve yielded a limit detection 4.88 μM quantification 16.3 μM, comparable or better than earlier reported sensors. work demonstrates promise MIP-based sensing. It also lays groundwork future investigations into optimizing PANI-MIPs nanocomposites develop more selective

Abstract A hydrazine (HYD) detection method is presented based on molecularly imprinting polymers (MIPs) and cobalt-barium stannate nanoparticles incorporated-functionalized MWCNTs (CBSNPs/f-MWCNTs) nanocomposite. Firstly, co-precipitation sonication techniques were applied to the preparations of CBSNPs CBSNPs/f-MWCNTs nanocomposite, respectively. Since waste generation occurs at a minimum level in these techniques, an environmentally friendly nanocomposite was prepared. After glassy carbon electrode modification with HYD imprinted electrodes fabricated using cyclic voltammetry (CV) dispersion containing 100.0 mM pyrrole (Py) monomer 25.0 molecule. The resulting electrochemical sensor demonstrated span 1.0 × 10 −9 M −8 achieved limit (LOD) 3.0 −10 M. Furthermore, developed used for actual tap water samples, obtained values close 100.00% recovery experiments showed high accuracy real sample analysis. Finally, selectivity, stability, reproducibility created investigated, has been have stability least 7 weeks, relative standard deviation (RSD) value 0.14%, selectivity samples. Graphical
