Abstract

<jats:p>Surfactant assisted co-precipitation method active for preparing ZnMnO<jats:sub>3</jats:sub> perovskites. The as- synthesized nanoflakes are well characterized by using numerous microscopic and spectroscopic methods which confirmed that ZnMnO<jats:sub>3</jats:sub> has high crystalline nature, desired functional groups with nanoflakes like morphology. The synthesized ZnMnO<jats:sub>3</jats:sub> were fabricated as the electrode material to determine biologically important as well as priority organic pollutant N- hydroxysuccinimide (NHS). The improved sensing performance of ZnMnO<jats:sub>3</jats:sub> towards NHS with outstanding sensitivity, and selectivity in the presence of a 50-fold excess concentration of metal ions and amino acids. The NHS sensor at ZnMnO<jats:sub>3</jats:sub>/GCE exhibits wide dynamics ranging from 0.01 <jats:italic>μ</jats:italic>M to 530.6 <jats:italic>μ</jats:italic>M with a superior detection limit of 0.04 <jats:italic>μ</jats:italic>M. Furthermore, the proposed sensor has utilized by practical applicability of NHS detection in the spiked urine samples that achieved better recoveries.</jats:p><jats:p><jats:inline-formula><jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="jesad0ba9-ga.jpg" xlink:type="simple" /></jats:inline-formula></jats:p>
