In this study, a flexible glove‐based electrochemical sensor as a wearable point‐of‐use screening tool has been fabricated for defense and food security applications. To design the wearable glove‐based sensor, we drew conductive patterns on the fingers of a rubber glove via gold@silver‐modified graphene quantum dots (Au@Ag core‐shell/graphene quantum dots [GQDs]) nano‐ink with optimal thickness. Then, this platform is combined with a portable electrochemical analyzer for on‐site detection of trifluralin pesticide in the range of 10 nM to 1 mM with the low limit of quantification (LLOQ) of 10 nM. The high efficiency and distinction of the trifluralin at specified concentrations in real leaf and apple samples were performed by simply touching with the glove and in spikes solution by immersing of fingertips. With their high sensitivity, selectivity, rapid, and easy operation pesticide analysis, these glove‐embedded sensors can also be engaged in on‐site monitor of other chemical threats and can be expanded to water and environmental samples.
