Magnetic nanoparticles could be key to effective immunotherapy

In recent years, researchers have hotly pursued , a promising form of treatment that relies on harnessing and training the body’s own immune system to better fight cancer and infection. Now, results of a study led by investigators suggests that a device composed of a magnetic column paired with custom-made may hold a key to bringing immunotherapy into widespread and successful clinical use. A summary of the research, conducted in mouse and human cells, appears online July 14 in the journal ACS Nano.
