'Lab-On-A-Glove' Could Bring Nerve-Agent Detection to a Wearer's Fingertips
Now researchers have developed a fast way to detect the presence of such compounds in the field using a disposable “lab-on-a-glove.” The report on the glove appears in the journal ACS Sensors.

The new wearable, flexible glove biosensor carries out the sampling and electrochemical biosensing steps on different fingers, with the thumb finger used for collecting the nerve-agent residues and an enzyme immobilized on the index finger. The researchers created stretchable inks to print the collection and sensing elements on these fingers.
Detection of the collected residues is performed when the thumb touches the printed enzyme-based organophosphate biosensor on the glove index finger. So, a user would swipe the thumb of the glove on a surface for testing, then touch the thumb and index fingers together for the electrochemical analysis.
