Chronic diseases such as diabetes and neurodegenerative disorders present growing global challenges, and there is an urgent need to find better solutions. My focus is on two key areas: the development of a transdermal patch for diabetes management and the exploration of nanorobots capable of crossing the blood-brain barrier to treat neurodegenerative diseases. By addressing the prevention of these conditions and improving treatment precision, we aim to alleviate the burden on millions of individuals. The question remains : How can we further leverage these innovations to redefine the future of healthcare?
