‘Smart’ contact lenses that have the potential to diagnose early stage cancer through tumour identifying chemicals found in tears have been created by scientists. The technology captures transporters called ‘exosomes’, which are tiny bubble-like messengers contained within cells in our bodies secreted into blood, saliva, urine, and tears. Exosomes can influence tumour regulation, progression and spread – offering hope of more targeted and effective treatment. the next generation smart contact lens is a promising “easy-to-use, rapid, noninvasive monitoring platform of cancer pre-screening and supportive diagnosis.” How will this really impact the fight against cancer?
