Bionic plants that can detect explosives in real time could be the future of environmental monitoring and urban farming, researchers said in a new study.
The spinach plants have carbon-nanotube-based nanoparticles in their leaves that give off infrared light and are sensitive to the presence of nitroaromatics, key components of several explosives, the scientists said.
If these chemicals are present in groundwater, they are absorbed by the roots and transported to the leaves, where they cause the infrared emissions of the so-called “nanosensor” to decrease.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
