“Towards Single Molecule Protein Sequencing”
We are developing a single molecule protein sequencing technology that aims to combine the advantages of mass spectrometry with those of nanopores. The basic idea is to cleave the individual amino acids from a protein molecule as they transit a small hole in sequence, and then identify each one by determining its mass-to-charge ratio in a mass spectrometer. In this talk, I will describe nanopore sensors, our protein sequencing concept, the development of a prototype nanopore mass spectrometer, and the results of studies of the transfer of single ions from liquid into vacuum from the nanoscale orifice of a charged needle. I will also describe some fundamental aspects of fluid mechanics that we have encountered as we pushed fluidic technologies down to the nanometer scale.
