3D‐Architectured MoS 2 ‐Microflower‐Modified Electrodes toward Electrochemical Determination of Imidacloprid
We report the fabrication and analytical performance studies of electrochemical sensors based on hydrothermally grown 3D MoS 2 ‐microflower‐modified Glassy Carbon (GCE) and Carbon Paste Electrodes (CPE) for the sensitive detection of the insecticide imidacloprid (IMI). As compared to MoS 2 /GCE, the...
