Scientists have reworked the humble spinach plant right into a bomb detector.
By embedding tiny tubes in the plants’ leaves, they are often made to select up chemicals referred to as nitro-aromatics, which are present in landmines and buried munitions.
Actual-time info can then be wirelessly relayed to a handheld device.
The MIT (Massachusetts Institute of Know-how) work is published within the journal Nature Materials.
The scientists implanted nanoparticles and carbon nanotubes (tiny cylinders of carbon) into the leaves of the spinach plant. It takes about 10 minutes for the spinach to take up the water into the leaves.
To learn the sign, the researchers shine a laser onto the leaf, prompting the embedded nanotubes to emit near-infrared fluorescent light.
This can be detected with a small infrared camera related to a small, low-cost Raspberry Pi pc. The signal can also be detected with a smartphone by removing the infrared filter most have.
