New Sensors Could Boost Radiotherapy

Nanoparticles and 3D cell cultures combine to help optimise treatment

Research led by Dr Colin Campbell could help improve radiotherapy treatments for cancer.

The study used 3D cell cultures to better model the effect of radiation on human cancer cells. Gold nanoshell sensors were used to track the effectiveness of treatment and the study found that using 2 half-doses of radiation rather than one large dose was more effective in destroying the cancer cells.

The sensors give information in real time, allowing doctors to monitor the treatment as it occurs.

This exciting research could give us a greater understanding of how radiotherapy affects tumours. By working so closely with our colleagues at the Edinburgh Cancer Centre, we have an opportunity to translate our findings into clinical practice.
