Nanopores may one day help doctors perform quick analysis of blood samples

Having blood drawn and analyzed to diagnose disease is a process that can take a few days, but what if your doctor could perform this analysis in moments, right before your eyes? That's the promise of "lab on a chip" technology, and researchers are working on a variety of fronts to remove technical roadblocks.

Bottom-up approach provides first characterization of pyroelectric nanomaterials

By taking a "bottom-up" approach, researchers at the University of Illinois at Urbana-Champaign have observed for the first time that "size does matter" in regards "pyroelectricity" - the current/voltage developed in response to temperature fluctuations that enables technologies such as infrared sensors, night-vision, and energy conversion units, to name a few.

Living cells behave as fluid-filled sponges

Scientists from the London Centre for Nanotechnology at UCL have shown that animal cells behave according to the theory of poroelasticity when mechanically stimulated in a way similar to that experienced in organs within the body. The results indicate that the rate of cell deformation in response to mechanical stress is limited by how quickly water can redistribute within the cell interior.
