University of Delaware researchers develop cancer 'nanobomb'

ey or accumulates in the blood vessels, the nanoparticles might cause blockage and create problems, Panchapakesan said. Furthermore, the nanobomb route is probably the only way to use nanotubes without any cytotoxicity as the nanotubes are destroyed completely.

Current surgical techniques are not precise and cancerous cells are often left behind. In addition, cancers in some part of the body, such as arteries and veins, are sometimes considered inoperable. Nanobombs can be used to target any remaining cancerous cells and can be used in any part of the body, allowing the creation of nanobomb therapy for a wide variety of cancers.

Panchapakesan said the method is far better than modern chemotherapy, which is non-selective, kills normal cells as well as cancerous cells and leads to a decline in the quality of life for the patient. "This is valuable in patient management, pain management and overall quality of life," he said.

Furthermore, Panchapakesan said, the nanobomb is a "very simple technique" and as such will likely prove to be "more robust and with the best chance to succeed."

Panchapakesan added, "We are just getting started in this area. There is plenty of work ahead to successfully translate this into clinical medicine." In addition to treatment, he believes nanotechnology can provide new tools for cancer diagnosis through the use of tiny nanosensors.

"In the future, my vision is that people will have at-home kits that can detect cancer. After work they will be able to go to a clinic, be treated with nanobombs and go home," Panchapakesan said. While these initial experiments are on breast cancer cells, he is also working to extend his method to prostate cancer and pancreatic cancer.

He also foresees nano-bio-robots or nano-surgical tools that can be placed inside the body to remove tumors in areas previously inaccessible using traditional treatment methods.
