The microchip relies on a fluorescence-based method for detecting the antibodies. The team’s innovation is that the glass plates forming the base of each microchip are coated with an array of nanoparticle-sized islands of gold, which intensify the fluorescent signal, enabling reliable antibody detection allowing doctors to quickly and cheaply track their patients’ auto-antibody levels before they show symptoms.
