Nanoparticles Unlock Tumor Identity March 28, 2010 (PhysOrg.com) — Using nanoparticles designed to recognize specific sugar-binding molecules on the surfaces of cells, a team of investigators at Michigan State University has developed a process that uses magnetic resonance imaging (MRI) to unlock the sugar-based code that identifies different types of cancer and normal cells. This [...]
Fat clue to TB awakening March 28, 2010 Macrophages infected with Mycobacterium tuberculosis that have been transformed to express the red fluorescent protein (constitutively), and the green fluorescent protein in response to stress from low pH.
