ABSTRACT: A flexible glove-based electrochemical biosensor

with highly stretchable printed electrode system has been

developed as a wearable point-of-use screening tool for defense

and food security applications. This disposable-mechanically

robust “l(fā)ab-on-a-glove” integrates a stretchable printable

enzyme-based biosensing system and active surface for swipe

sampling on different fingers, and is coupled with a compact

electronic interface for electrochemical detection and real-time

wireless data transmission to a smartphone device. Stressenduring

inks are used to print the electrode system and the

long serpentine connections to the wireless electronic interface.

Dynamic mechanical deformation, bending, and stretching studies

illustrate the resilience and compliance of the printed traces

against extreme mechanical deformations expected for such onglove

sampling/sensing operation. An organophosphorus hydrolase (OPH)-based biosensor system on the index finger enables

rapid on-site detection of organophosphate (OP) nerve-agent compounds on suspicious surfaces and agricultural products

following their swipe collection on the thumb finger. The new wireless glove-based biosensor system offers considerable promise

for field screening of OP nerve-agents and pesticides in defense and food-safety applications, with significant speed and cost

advantages. Such “l(fā)ab-on-a-glove” demonstration opens the area of flexible wearable sensors to future on-the-hand multiplexed

chemical detection in diverse fields.
