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.

Radiolabeled nanoparticles boost PET-CT combo imaging

In an attempt to decrease the amount of cancer-targeting nanoparticle needed to image tumors, a team of investigators has developed a simple method for creating iron oxide nanoparticles labeled with 18F, a radioisotope that is easily detected using positron emission tomography.

Pack 'em in - gold nanoparticles improve gene regulation

Investigators at Northwestern University have found that packing small interfering RNA (siRNA) molecules onto the surface of a gold nanoparticle can protect siRNAs from degradation and increase their ability to regulate genes involved in cancer.

Making the smallest, most perfect polymer films

Like many creative but essentially conservative scientists, Tom Russell of the University of Massachusetts Amherst, in more than 30 years of polymer science research, would rarely use the term 'truly transformative' about his work. Until now.
