NTs have proved able to transport a wide range of molecules across membranes and into living cells; therefore, they have attracted great interest in biomedical applications such as advanced imaging, tissue regeneration, and drug or gene deliver.

Once functionalized, they can be employed as agents for targeted drug delivery, cell imaging, vaccine delivery, tumor targeting, and tissue regeneration.

Carbon nanotubes are an allotropic form of carbon identified in 1991 by Iijima and since widely studied and used for a wide range of applications such as materials reinforcement, electrode materials and/or components for nanoelectronics (biosensors) or even (which could be remotely activated in some cases) drug carriers in biomedicine.

Abstract. In the past decade, there has been phenomenal progress in the field of nanomaterials, especially in the area of carbon nanotubes (CNTs). In this review, we have elucidated a contemporary synopsis of properties, synthesis, functionalization, toxicity, and several potential biomedical applications of CNTs.

Among the various nanomaterials, carbon nanotubes (CNTs) have gained increased attention in the field of drug delivery–based medicines due to their tiny nanoneedle tubular, small nano size, biodegradable, nonimmunogenic biocompatible, high aspect ratio, high drug loading, better stability, purity, and optical inheritance.
