Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.

Microfluidic device mimics tumor microenvironment, helps drug discovery

One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor.
