A new study has shown that adding boron-nitride(氮化硼) nanotubes to the surface of cancer cells can double the effectiveness of Irreversible Electroporation, a minimally1 invasive treatment for soft tissue tumors in the liver, lung, prostate, head and neck, kidney and pancreas. Although this research is in the very early stages, it could one day lead to better therapies for cancer. The study was carried out by researchers in Italy at the Institute of Life Sciences, Scuola Superiore Sant'Anna in Pisa with BNNTs provided by researchers at NASA's Langley Research Center, the Department of Energy's Thomas Jefferson National Accelerator Facility and the National Institute of Aerospace3.

Irreversible Electroporation is a new therapy for difficult-to-treat cancers in soft tissues. It is offered in many cancer treatment centers across the United States, and is being studied for effectiveness on a wide variety of specific cancers. Researchers at the Institute of Life Sciences began experimenting with BNNTs to see if the nanotubes could make the treatment more effective.

"Irreversible Electroporation is a way of putting holes in the wall of a tumor2 cell," said Michael W. Smith, chief scientist at BNNT, LLC and formerly4 a staff scientist at NASA's Langley Research Center.

Smith explained that when a hole of proper size is made in the wall of a cell, the cell reacts in a predictable fashion. Although the exact mechanism5 has not been pinpointed6, researchers suspect that such a hole could trigger cell suicide. "The cell will literally7 go, Oh, something's terribly wrong, and kill itself. That's called apoptosis(细胞凋亡) ," he added.
