Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

from (e) Science News

Scientists have designed a new self-assembling nanoparticle that targets tumors, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of magnetic resonance imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells. The nanoparticle is coated with a special protein, which looks for specific signals given off by tumors, and when it finds a tumor it begins to interact with the cancerous cells. This interaction strips off the protein coating, causing the nanoparticle to self-assemble into a much larger particle so that it is more visible on the scan. more
