Quantum dots provide quantitative profile of pancreatic cancer biomarkers on single cells

With the aid of a novel set of lipid-coated, targeted quantum dots, researchers at Johns Hopkins University have developed a method for quantifying multiple specific biomarkers on the surfaces of individual cancer cells. This approach to quantitative biomarker detection stands to improve the histopathology methods used to diagnosis pancreatic and other cancers and enable the development of methods to spot cancer cells circulating in the blood stream.

Crushing pressure, swelling pores

By squeezing a porous solid, scientists surprisingly made its cavities open wider, letting in - and trapping - europium ions. Given the similarities between europium and uranium ions, the team, based at the University of South Carolina, Yonsei University (Korea), and Stanford University, thinks the innovation could represent a promising new avenue for nuclear waste processing.
