(Phys.org) —UNSW chemical engineers have synthesised a new iron oxide nanoparticle that delivers cancer drugs to cells while simultaneously monitoring the drug release in real time.
Game-changing nanodiamond discovery for MRI
A Northwestern University study shows that coupling a magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast.
Engineers develop more effective MRI contrast agent for cancer detection
Many imaging technologies and their contrast agents chemicals used during scans to help detect tumors and other problems involve exposure to radiation or heavy metals, which present potential health risks to ...
Overcoming cancer drug resistance with nanoparticles
One of the ways in which cancer cells evade anticancer therapy is by producing a protein that pumps drugs out of the cell before these compounds can exert their cell-killing effects. A research team at Northwestern University ...
