Researchers from Brown University and the
University of Rhode Island have demonstrated a promising new way to
increase the effectiveness of radiation in killing cancer cells.
The approach involves gold nanoparticles tethered to acid-seeking
compounds called pHLIPs. The pHLIPs (pH low-insertion peptides) home in
on high acidity of malignant cells, delivering their nanoparticle
passengers straight to the cells’ doorsteps. The nanoparticles then act
as tiny antennas, focusing the energy of radiation in the area directly
around the cancer cells.
In a paper published in the Proceedings of the National Academy of Sciences, the research team shows that the approach substantially increases the cancer-killing power of radiation in lab tests.
