Nanoparticles offer new hope for cancer detection, treatment

Magnified nanoparticlesSpecially designed nanoparticles can reveal tiny cancerous tumors that are invisible to ordinary means of detection, according to a study by researchers at the School of Medicine. Researchers demonstrated that very small human melanoma tumors growing in mice — indiscernible from the surrounding tissue by direct MRI scan — could be “lit up” and easily located. Because the nanoparticles can be engineered to carry a variety of substances, they also may be able to deliver cancer-fighting drugs to malignant tumors.
