Since, their discovery, carbon nanotubes (CNTs) have been eminent members of
the nanomaterial family. Because of their unique physical, chemical and mechanical
properties, they are widely predicted and regarded as new potential materials to bring
enormous benefits in cell biology studies1. Also, an increasing number of reports
have studied the toxicological impact and safety profile of carbon nanomaterial on
both plant2 and mammalian cells, indicating that a high degree of CNT functionalization
leads to a dramatic reduction in toxic effects3.
