Ask a Scientist – Nano expert: Nicole Steinmetz

Nicole Steinmetz, an associate professor at Case Western Reserve University, introduces nanomaterials, which are materials on the nanometer scale. She explains the size scale, noting that a nanometer is 10 to the minus 9 meters. Naturally occurring nanomaterials include DNA, proteins, and viruses. Viruses are used in medical engineering to deliver medicines to specific cells and tissues.
