Rice University scientists have developed a way of tracking single-walled carbon nanotubes under the skin that can pintpoint the location of cancer tumors. The nanotubes can be made to gather within tumors in higher concentrations than the rest of the body using attached antibodies, but spotting these nanostructures in vivo can be difficult.
Previously, it’s been possible to identify the location of the nanotubes under the skin, but not their depth. The researchers are now using a technique called spectral triangulation to be able to identify exactly where the nanotubes are bunching up.
