Critical Thinking - How we can use nanotubes in place of copper wires

How Carbon nanotubes wires can be used in inductors?
The inductors which are made up of carbon Nanotube (CNT) have been proposed. Though the fabrication of the proposed inductor are still challenging and has many problems also, merits of the proposed inductor are as following:
(i)The magnetic field induced by current in CNT is about one thousand times larger than the current in normal copper wire.
(ii)The large magnetic field in the large inductance, according to relation between magnetic field and inductance.
(iii)The inductor made up of CNT is smaller than inductor in IC circuits , because the CNT can be bent with small curvature.

How Carbon nanotubes can be used in medical purposes ?
CNT's exhibits dimensional and the chemical compatibility with biomolecules , such as DNA and proteins. CNT's enable fluorescent and photoacoustic imaging and as well as localized heating using near-infrared radiation. CNT enabled the x-ray sources for medical imaging are also in development. Relying on the unique properties of CNT's , researchers have developed field emission cathodes which allow precise x-ray control and close placement of multiple sources.
Concern :
CNT toxicity remains a concern, although CNT biocompatibility may be engineerable. Medical approval of CNT's requires understanding of immune response and appropriate standards for inhalation, injection, ingestion and skin contact. CNT's forests immobilized in a polymer did not show elevated inflammatory response in rats relative to controls.

IN CHEMICALS:
CNT can be used for desalination. Water molecules can be separated from salt through electrochemically robust nanotube with controlled nanoscale porosity. This process requires far far lower pressures than conventional reverse osmosis methods.
