A close look at Bionanotechnology MCCB October 21 2011 Thomas L. Deits, Ph.D.
What is nanotechnology? • Any process or product that involves analysis or manipulation of materials at the nanometer scale
Your fingernail is about as thick as 500 E. coli, each of which is as thick as 500 1- nanometer slices
E. coli with Pili and Flagella Ang L National University of Singapore http://www.icmm.csic.es/spmage07/spmageview.php?id=50
Why is the nanometer scale important? Virtually every property of matter that we care about arises at the nanometer scale: Color Odor Strength Flexibility Conductivity Durability Biological activity
Bionanotechnology • Biology happens • at the nanoscale: • DNA • enzymes • muscles • nerves • senses
Biology is a Big Idea in Nanotechnology • Size and Scale • Structure of Matter • Forces and Interactions • Quantum Effects • Size-Dependent Properties • Self Assembly • Tools and Instrumentation • Models and Simulations • Science, Technology and Society The Big Ideas of Nanoscale Science and Engineering S.Y.
