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 ...

Biocompatible quantum dot images tumors in live animals

Quantum dots, small semiconductor nanoparticles that fluoresce brightly with sharply defined colors, have tremendous promise as biomedical imaging agents except for one problem—most are made from potentially hazardous ...

Nanoparticles harvest invisible cancer biomarkers

(PhysOrg.com) -- Cancer biologists have long presumed that tumor cells shed telltale markers into the blood and that finding these blood-borne biomarkers could provide an early indicator that cancer is developing somewhere ...

Polymeric nanoparticles attack head and neck cancer

Head and neck cancer, the sixth most common cancer in the world, has remained one of the more difficult malignancies to treat, and even when treatment is successful, patients suffer severely from the available therapies. ...

Nanoparticles working in harmony

For decades, researchers have been working to develop nanoparticles that deliver cancer drugs directly to tumors, minimizing the toxic side effects of chemotherapy. However, even with the best of these nanoparticles, only ...

Hand-held NMR instrument yields rapid analysis of human tumors

Using a handheld molecular imaging device in combination with magnetic nanoparticles and a smartphone, a team of investigators from the Massachusetts General Hospital and Harvard Medical School has developed a fast, portable ...
