Abstract:
Human behavior depends on the action and interaction of trillions of micron-scale biological cells. To better understand how these cells operate and cooperate in complex biological systems, there is a need for new experimental tools that can scale both to the small size of individual cells and to the large numbers of cells contained in cellular networks. In this talk, I will describe how nanofabrication technology can be used to create new bio-interfaces with feature sizes and densities comparable to biological cell networks. In particular, I will discuss how vertical silicon nanowires can penetrate the cellular membrane to provide a physical interface to the interiors of living cells. This intracellular interface allows us to probe the chemical and electrical activity of many individual cells in parallel. I will show how these new capabilities can be used to reverse engineer neuronal circuits and discover internal biochemical signaling cascades.

Jacob Robinson
Jacob T. Robinson is a postdoctoral fellow in the Department of Chemistry
and Chemical Biology at Harvard University. He received a BS in Physics from
UCLA and a PhD in Applied Physics from Cornell University. As a doctoral
student he studied light confinement and light-matter interaction in
nanofabricated silicon photonic devices.
His current research is focused on using silicon nanofabrication technology
to create new devices for biological research.
