Carbon nanotubes forecast when vegetables spoil and buds bloom

Abstract:
This is where the CNTs come in. Single-walled CNTs have several attributes that make them well-suited for sensing processes that involve the transfer of electrons – the basis of any chemical reaction. The CNTs Fong and Swager and their colleagues worked with are p-type semiconductors, so n-type dopants – anything that donates electrons to the CNT – will diminish their conductivity. The CNTs’ curved graphene surface also makes their electronic properties incredibly sensitive to dopants in their environment.
