The Indian Institutes of Technology, Bombay and Indore, have jointly developed a biosensor that makes it possible to detect kidney disorders in less than 8 minutes. The biosensor can accurately measure both the pH and urea concentration with a single drop of urine. The researchers who developed it say that it will help make a point-of-care test to determine whether the kidneys are functioning normally. The biosensor is made by encapsulating an enzyme urease and a molecule FITC-dextran in alginate microspheres. The combination glows in response to a chemical reaction with urea and changes in pH when urine is added.
