Urine Test Detects Organ Transplant Rejection, Could Replace Needle Biopsies | Research Horizons

New nanoparticle makes urine glow as soon as T cells initiate an attack on transplanted organs Glowing pee may replace the biopsy needle: In detecting organ transplant rejection, a new nanoparticle has proven much faster and more thorough in the lab than a biopsy. When T cells mount their first attack on the organ's cells the nanoparticle sends an alarm signal into the urine that makes it fluoresce. Bioengineering and Bioscience Electronics and Nanotechnology
