Physicochemical properties of CNTsĬarbon nanotubes are a huge cylindrical large molecules consisting of a hexagonal arrangement of sp 2 hybridized carbon atoms (C-C distance is about 1.4 Ǻ). In this chapter, the works that have been carried out with CNTs in the field of cancer therapy are briefly introduced. Unlike other naocarriers, such as liposomes/micelles that emerged in the 1960s and nanoparticles/dendrimers that emerged in 1980s, it has emerged no more than 20 years for carbon nanotubes to be envisaged as target drug carriers. Apart from their uses in the cellular imaging with diagnostic effects in nanomedicine, CNTs are promising drug carriers in the target drug delivery systems for cancer therapies. The unique physicochemical properties of CNTs with easy surface modification have led to a surge in the number of publications in this interesting field. CNTs belong to the fullerene family of carbon allotropes with cylindrical shape. The requirements for new drug delivery systems to improve the pharmacological profiles while decreasing the toxicological effects of the delivered drugs have also envisaged carbon nanotubes (CNTs) as one of the potential cargos for the cancer therapy. With the development of nanotechnology, few nanomaterial-based products have shown promise in the treatment of cancers and many have been approved for clinical research, such as nanoparticles, liposomes, and polymer-drug conjugates. The development of such a system is not dependent only on the identification of special biomarkers for neoplastic diseases but also on the constructing of a system for the biomarker-targeted delivery of therapeutic agents that avoid going into normal tissues, which remains a major challenge. However, most of this research is still in the preclinical stage and the successful clinical implementation is still in a remote dream. Hence, considerable efforts are being directed to such a drug delivery system that selectively target the cancerous tissue with minimal damage to normal tissue outside of the cancer focuses. Inadequacies in the ability to administer therapeutic agents with high selectivity and minimum side effects largely account for the discrepancies encompassing cancer therapies. However, despite astounding advances in fundamental cancer biology, these results have not been translated into comparable advances in clinics. Over the past few decades, the field of cancer biology has progressed at a phenomenal rate.

Chemotherapy with anticancer drugs is the main auxiliary treatment but often fails because of their toxic and side effects that are not endurable for the patients.

Surgery can remove cancer focuses but cannot do the same for the micro-focuses and neither can extinguish the free cancer cells that are often the origin of relapse. Here, we review the progress in the study on the application of carbon nanotubes as target carriers in drug delivery systems for cancer therapies.Ĭancers are a kind of the diseases that are hardest to cure, and most cancer patients definitely die even when treated with highly developed modern medicinal techniques. The transporting capabilities of carbon nanotubes combined with appropriate surface modifications and their unique physicochemical properties show great promise to meet the three pre-requisites.

An ideal carrier for target drug delivery systems should have three pre-requisites for their functions: (1) they themselves have target effects (2) they have sufficiently strong adsorptive effects for anticancer drugs to ensure they can transport the drugs to the effect-relevant sites and (3) they can release the drugs from them in the effect-relevant sites, and only in this way can the treatment effects develop. Generally speaking, such a system is often made up of the carriers and drugs, of which the carriers play the roles of target delivery. To realize target treatment, the first step of the strategies is to build up effective target drug delivery systems. This selective delivery of the drugs has been called target treatment. Obviously, the therapeutic effects will be revolutionarily improved if human can deliver the anticancer drugs with high selectivity to cancer cells or cancer tissues. Although chemotherapies are successful in some cases, systemic toxicity may develop at the same time due to lack of selectivity of the drugs for cancer tissues and cells, which often leads to the failure of chemotherapies.

Among all cancer treatment options, chemotherapy continues to play a major role in killing free cancer cells and removing undetectable tumor micro-focuses.
