Direct spun aligned carbon nanotube web-reinforced proton exchange membranes for fuel cells
A composite membrane prepared by electrospinning SPEEK and direct spinning of CNTs is more robust than SPEEK alone and outperforms SPEEK and Nafion 212 membranes.</p
Wearable Flexible and Stretchable Glove Biosensor for On-Site Detection of Organophosphorus Chemical Threats
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 “lab-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. Stress-enduring 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 on-glove sampling/sensing operation. An organophosphorus hydrolase
(OPH)-based biosensor system on the index finger enables rapid <i>on-site</i> 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 “lab-on-a-glove” demonstration
opens the area of flexible wearable sensors to future on-the-hand
multiplexed chemical detection in diverse fields
