New ‘molecular flashlight’ technique detects brain metastases in mice using ultra-thin light probe

Monitoring molecular changes in the brain caused by cancer and other neurological pathologies in a non-invasive way is one of the major challenges in biomedical research. A new experimental technique has achieved this by introducing light into the brains of mice using an ultra-thin probe. The study is published in the journal Nature Methods by an international team that includes groups from the Spanish National Cancer Research Centre (CNIO) and the Spanish National Research Council (CSIC).
