an electrochemical sensor based on snse nanosheets and ionic liquids for the selective detection of n-acetylcysteine

To detect n-acetylcysteine (n-ac), a voltammetric sensor was developed employing a carbon paste electrode (cpe) modified with snse nanosheets (snse nss) and ionic liquids (ils). compared to the unmodified cpe, the electrochemical sensor (snse nss/ils/cpe) exhibited significantly higher current responses for n-ac oxidation. using linear sweep voltammetry (lsv), cyclic voltammetry (cv), chronoamperometry, and differential pulse voltammetry (dpv), the electrochemical properties of the sensor and the oxidation behavior of n-ac were investigated. with a detection limit (lod) of 0.02 µm (s/n = 3), dpv, a sensitive analytical method for n-ac quantification, showed a linear relationship between n-ac concentration and peak current spanning the range of 0.05 µm to 480.0 µm. in addition, the sensor demonstrated adequate stability and repeatability. with recovery rates ranging from 91.40% to 106.30%, it was effectively used to determine n-ac in actual samples.
