Heavy Metal Ion Sensing

The sensing properties of heavy metal ions by macrocycle-based fluorosensors are sensitive not only to cation–receptors and cation–fluorophore interactions but also to cation–anion (endo/exo-coordination modes) and/or cation–solvent interactions.

AbstractWe report the change to the band structure of two types of carbon nanotubes due to the presence of an isolated, non-conducting, uniformly charged shell held at a fixed distance above their surfaces. We find that, depending on the chirality of the nanotube, the strain on the lattice causes the dispersion relationships to change. This change can result in a modification of the band structure which can induce a metal-semiconductor transition. We consider these effects as a possible mechanism for heavy-metal ion sensing by functionalized carbon-nanotubes.
