Nanoparticles that cancer cells can't resist
Turning cancer cells into mini magnets by using nanoparticles could make biopsies so sensitive and efficient that there will be no need to repeat these invasive tests.
Biopsy results can be ambiguous: sometimes they can be negative simply because there are too few malignant cells in the sample to be detected - not because all trace of disease has gone. Now researchers from the University of New Mexico and the company Senior Scientific, both in Albuquerque, have come up with a solution that harnesses the power of magnetic attraction.
