Read moreMalignant cells are notorious for their ability to break away from a tumor, migrate to other seemingly targeted locations in the body, and establish new tumors, called metastases. The biochemical signals that guide tumor cell migration are poorly understood, but efforts to find those signals should receive a boost thanks to a new microfluidics device designed specifically to track how breast cancer cells move in response to chemical signals.

Read moreOne of the unique features of nanoscale materials is that they are often of the same size as most biomolecules, and thus can be used to study intracellular biochemistry without themselves having much of an impact on normal cellular function. Now, an international team led by investigators at McGill University has taken advantage of the small size of quantum dots to create a nanoscale device that can report on the oxidative conditions within a cell.
