摘要

•Synthesis and physicochemical characterization of silver nanoparticles (AgNP) assembled by layer by layer method on carbon nanofibers (CNF) surface complemented by a DFT study.•CV and SWV electrochemical sensor AgNP/CNF-CPE evaluation.•AgNP-CNF/CPE electrochemical sensor simultaneously detected sunset yellow and tartrazine dyes.•Validation of the AgNP/CNF-CPE electrochemical sensor using the UV-visible spectrophotometric technique.
