Nanomedicine Research at OU Roger Harrison, Ph.D. Professor School of Biomedical Engineering School of Chemical, Biological and Materials Engineering OU Health Sciences Center Biomedical Engineering Symposium March 24, 2017 What Is Nanomedicine? • Nanomedicine is the medical application of nanotechnology. • Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even future applications of molecular nanotechnogy such as biological machines. • Current problems for nanomedicine involve understanding the issues related to toxicity and environmental impact of nanoscale materials. • Distinct from the field of Molecular Medicine, a broad field where physical, chemical, biological, bioinformatics and medical techniques are used to describe molecular structures and mechanisms, identify fundamental molecular and genetic errors of disease, and to develop molecular interventions to correct them.
