A new imaging technology uses magnetism to noninvasively move nanoparticles inside the body. “What is novel about this whole approach and this work is that we’re using external magnetic forces to move nanoparticles within tissue, to modulate them,” Stephen Boppart explains. “Most other particles will localize somewhere and typically sit there,” he adds. “No other particle is dynamic like this, which is a unique way to generate contrast.” (Credit: Stephen Boppart, Alex Jerez, Zach Johnson/U.
