Pediatric diseases can be complex, and their treatments must be ultra-safe. To avoid side effects, reduce dosages, and report on outcomes, Georgia Tech researchers create complex but small structures – nanoparticles – that have multiple sophisticated functions in the body, such as engaging the immune system to fight infections, and reporting back on the patient’s condition. We help define and advance the field of “Pediatric Nanomedicine” and, with it, the creation of revolutionary new treatments.
