In the realm of medicine, nanotechnology has opened new avenues for diagnostics and treatment. Robert Langer is a prominent figure in this field. His work on drug delivery systems using nanoparticles has revolutionized how medications are administered, improving their efficacy and reducing side effects. Another notable innovator is Chad Mirkin, whose research on nanoparticle-based diagnostics has led to the development of highly sensitive techniques for detecting diseases at an early stage.
