Researchers develop new, rapid blood test to detect liver damage

Chemist Vincent Rotello at the University of Massachusetts Amherst, with colleagues at University College London (UCL), U.K., announce today that they have developed a "quick and robust" blood test that can detect liver damage before symptoms appear, offering what they hope is a significant advance in early detection of liver disease. Details appear in Advanced Materials.
