Carbon nanotubes as effective cancer killers

Abstract:
Curing cancer is on of the many promises of nanotechnology. Although scientists have been making amazing progress in this area, there are still significant challenges that need to be overcome before highly selective, targeted anti-cancer therapy becomes available for everyday clinical use. A nanotechnology-based system to eradicate cancer needs four elements: 1) Molecular imaging at the cellular level so that even the slightest overexpressions can be monitored; 2) effective molecular targeting after identifying specific surface or nucleic acid markers; 3) a technique to kill the cells, that are identified as cancerous based on molecular imaging, simultaneously by photodynamic therapy or drug delivery and 4) a post molecular imaging technique to monitor the therapeutic efficacy. One of the problems today is that these four techniques are used separately or ineffectively, resulting in an overall poor therapeutic outcome. In what could amount to a quantum leap in cancer nanotechnology, researchers have now integrated these techniques simultaneously in vitro and shown that this results in higher therapeutic efficacies for destroying cancer cells. Their demonstration of multi-component molecular targeting of surface receptors and subsequent photo-thermal destruction of cancer cells using single-walled carbon nanotubes (SWCNTs) could lead to a new class of molecular delivery and cancer therapeutic systems.
