Gas sensors are essential for personal safety and environmental monitoring, but traditional sensors have limitations in sensitivity and energy efficiency. Now, researchers have developed an improved gas-sensing technology by treating graphene sheets with plasma under different conditions, creating structural and chemical defects that enhance ammonia detection. These functionalized graphene sheets exhibited superior sensing performance compared to pristine graphene, potentially paving the way for wearable gas detection devices for everyday use.
