Charlie Johnson Group – University of Pennsylvania

Dr. Johnson’s research is focused on the nano-scaled transport properties (charge, energy, spin, etc.) of nanostructures and single molecules, including carbon nanotubes, graphene, DNA, synthetic proteins, and other biomolecules.  They are particularly interested in the physical properties of hybrid nanostructures and their use in molecular sensing.  Other research interests include the development of scanning probe techniques for electronic property measurement of nanomaterials and nanodevices.

Why Is Small So Big?

Nanotechnology deals with products and processes that are measured in almost unbelievably small increments called “nanometers”—one billionth of a meter.

At the nanoscale, materials differ from larger objects in their physical, chemical and biological properties; therefore, they lend themselves to new and improved materials, systems and devices. Nanotechnology is behind the development of such diverse advancements as:

  1. Drug Delivery
  2. Biofiltration and Separation sciences
  3. Improved coatings for medical devices

Thanks to rapid advances in this exciting new field, we now have the tools and talents to manipulate materials on the molecular scale—a technology literally changing the world as we know it.
