Abstract
Systems that can measure small changes in ion concentrations and method of manufacturing and using those systems. The system includes a substrate, a plurality of multi-walled carbon nanotubes, each multi-walled carbon nanotube from the plurality of multi-walled carbon nanotubes having two ends and a surface extending between the two ends, one of the two ends being disposed on and operatively attached to the substrate, the other of the two ends not being disposed on the substrate, a number of organic molecules; each organic molecule bound to one multi-walled carbon nanotube, each organic molecule also having an end group with affinity for a predetermined ion(s), and a substantially nonconducting polymer deposited on a portion of each multiwalled carbon nanotube, the portion substantially not including locations on each multiwalled carbon nanotube at which each organic molecule is chelated.
