Researchers have long sought to use magnetic fields to increase the concentration of drug-loaded iron oxide nanoparticles that reach a tumor. However, magnetic fields drop off quickly with distance, making it almost impossible to consider such an approach for tumors located more than a few centimeters from the skin. To solve what appears to be a fundamentally unsolvable problem, researchers have now taken a two-pronged approach, one that uses an external magnetic field and an implantable magnetizable mesh to create local magnetic fields strong enough to trap nanoparticles at a specific location.

One of the hallmarks of cancer is that tumors alter the tissues that surround malignant cells. A team of investigators from Johns Hopkins has taken advantage of this hallmark to develop a new approach to identifying cancer that hones in on collagen that gets degraded as a tumor grows.
