Scientists from the Pacific Northwest National Laboratory (PNNL) have developed a technique to force a variety of enzymes to self-assemble layer-by-layer on carbon nanotubes with the help of noodle-like polymer molecules.

In “A biosensor layered like lasagna,” the researchers say that this technique can be applied to a wide range of applications. In particular, it will be possible to build other biosensors “that react specifically with other biological chemicals, environmental agents or even microbes.”
