This smart contact lenses can diagnose cancer from tears
US scientists have developed a contact lens that can help in the early detection of cancer using tears and help in the treatment.The novel lens, developed by the team at the Terasaki Institute for Biomedical Innovation (TIBI) in California, is able to capture and detect exosomes, the nanometer-sized vesicles found in bodily secretions that have the potential for being diagnostic cancer biomarkers.The lens was designed with microchambers bound to antibodies that can capture exosomes found in tears. This antibody-conjugated…
