▎ 摘  要

NOVELTY - The device has a first working electrode (ET) with functionalized carbon surface pretreated on a ring finger, a second working electrode with surface functionalized with carbon nanospheres on an index finger, and a third working electrode with a functionalized surface of printex carbon on a middle finger, where preparation of the electrodes is made from a screen printing technique using a carbon conductive ink and nanomaterials such as single and/or multiple wall carbon nanotubes, graphene, graphene oxide, oxidized graphene oxide, reduced graphene oxide, carbon black, metallic nanoparticles of gold, platinum, palladium, ruthenium, nickel, copper, iron, vanadium and europium are used to modify a sensory surface. USE - Flexible glove-made sensor device for detecting pesticides e.g. carbendazim pesticides, diuron pesticides, paraquate pesticides, fenitrothione pesticides, triazines pesticides, substituted glycine pesticides, triazole pesticides, strobilurin pesticides, dinitroaniline pesticides (all claimed), chlorpyrifos, carbaryl, methomyl, atrazine, trifluralin, glyphosate and chloranil in samples of cabbage, apple, and commercially obtained orange juice, in supermarkets and food processing industry. Can also be used for environmental samples such as water, rivers, seas, streams and lakes. ADVANTAGE - The device can be manufactured with quick procedures in a short time. The device can be made by incorporation of the nanomaterials to the surface of the working electrode such that the nanomaterials can decrease potentials of electro-oxidation, promote an increase in conductivity and in electro-active area, thus improving the performance of the device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an electrochemical sensor produced in a complete disposable glove containing a working electrode, a reference electrode and an auxiliary electrode.(Drawing includes non-English language text).
