Electrochemical determination of dinitramine in water samples using a pencil graphite electrode modified with poly-l-cystein-gold nanoparticle

A nanoscale electrochemical guanine DNA-biosensor based on a flower-like nanocomposite of Tb-doped ZnO for the sensitive determination of pemetrexed

“…The aim is for bulky electrode systems to shi to smallsized electrochemical cell congurations. [19][20][21][22][23] Some scholars have utilized pencil graphite electrodes (PGEs) to detect diverse samples in numerous sample matrices. 24 Nonetheless, utilizing a bare PGE for electrochemical sensor uses would be followed by challenges caused by the poor transferability of electrons and passive properties of the charge transfer.…”
