Novel Imaging Technique Visualizes Potential Cancer Treatments in Action

A new and innovative imaging technique for observing cancer treatments in brain tumor cells has been developed by researchers at the Virginia Tech Carilion Research Institute (Roanoke, VA, USA).

The study was published in the March 3, 2015, online edition of the journal NANO Letters. The researchers used nanotechnology to target glioblastoma tumor stem cells which tend to survive existing cancer treatments and grow into new tumors.

The researchers isolated glioblastoma tumor stem cells in cultures, treated them with gold nanorod cancer therapy, and observed the results at the cellular level using in situ transmission electron microscopy.

"Zhi Sheng, assistant professor at Virginia Tech Carilion Research institute, said, "We've never been able to directly observe the actions of potential cancer treatments this way before. We can look at single-cell delivery of cancer treatments, and see how the individual cells respond. If we can learn how to kill these cells, we should be able to improve our chances of developing effective treatments by being able to directly observe the effects of the possible therapeutics."
