Our research into nanoscale electronics is both fundamental and applied. Our goal is to open new doors for investigation of physics at the nanoscale, and to discover solutions to the engineering problems that future technologies will face. Here are some of the general research areas we work on:


Nanomaterials -
Synthesis & Characterization
Researchers around the world have learned to make a range of nanomaterials.
Which nanomaterials are most interesting?
Which ones have unexpected behaviors? We often don't know until we start measuring!




Nanoscale
Electronics
Nanoscale electronic circuits continue to surprise us with unexpected behaviors and challenges. It's hard to control circuits when every molecule matters! Sensitivity and variability are a challenge but also an opportunity.
What new types of devices are possible at the nanoscale?
Much of our work focuses on the amazing sensitivity of nanodevices to their environment and consequences for chemical sensing.




Single Molecule
Devices
We use the world's smallest wires to electrically connect to single molecules. The devices are so sensitive that we can watch chemistry happening in real time, molecule- by-molecule.
Single molecules as circuits?
Yes, in fact, single molecule circuits have been imagined for many years! Our particular method makes stable circuits so that a single molecule can be monitored for long periods of time as it interacts with its environment.




Single Molecule
Molecular Biology
When a circuit is made with a single protein, we get an electrical signal that reveals all of that protein's complex activity. Beyond being a new way of thinking about "electronics," these devices are a promising new method for revealing the complex interactions between molecules like proteins and pharmaceuticals. As an example of how this works, see our short YouTube video about lysozyme or listen to a complete lecture by Prof. Collins.
