Abstract
Laser-induced graphene was produced and studied to determine sufficient specifications for creating a sensor. This sensor is made of porous three-dimensional graphene foam, the defects of which function as gas-solid interaction sites. Volatile organic compounds (VOCs) that bind with these sites can change the sensor's resistance (which changes the voltage produced when a current is run through the sensor). It is possible to monitor VOC concentrations over time by collecting voltage data. Studying which VOCs the plant sagebrush releases in response to what environmental stressors will teach biologists about the plant and hopefully enable them to protect it.
