DISTINGUISHED LECTURE IN BIOLOGICAL ENGINEERING
Abatract:
Nanotechnology offers many opportunities to contribute to biology. Here I will present examples where nanofabrication – the ability to make confined structures with dimensions at will – is used to examine the biophysics of single molecules and cells. I will present two major examples from our lab:
1. DNA translocation through solid-state nanopores [1]
Solid-state nanopores have proven to be a surprisingly versatile probe for single-molecule analysis of DNA. I will describe some of our recent efforts to expand the capabilities of solid-state nanopores even further, in the direction of single-protein detection, graphene nanopores, plasmonic nanopores, and DNA origami nanopores.
2. Exploring biophysics of bacteria with nanofabricated shapes [2]
We shape bacteria into forms that deviate from their natural phenotype. Specifically, I will show our ability to shape live E. coli bacteria into novel shapes such as rectangles, squares, triangles and circles. We study pattern formation in these geometries. I will show spatiotemporal oscillations of Min proteins – associated with cell division – in such artificial geometries of live E. coli cells.
