A pioneering Scottish technology that could dramatically speed up the development of life-saving cancer treatments has secured a £750,000 seed investment.  ScreenIn3D, a spin-out of the University of Strathclyde, has developed a groundbreaking "lab-on-a-chip" system that allows drug developers to test dozens of cancer therapies on tiny patient-derived tumour samples - offering a faster, easier and more accurate alternative to animal testing.
