324:. In collaborative work with Mark Akeson, a post-doctoral student at the time, the two established methods for monitoring proton permeation through ion channels such as gramicidin. In 1989, while returning from a scientific meeting in Oregon, Deamer conceived that it might be possible to sequence single molecules of DNA by using an imposed voltage to pull them individually through a nanoscopic channel. The DNA sequence could be distinguished by the specific modulating effect of the four bases on the ionic current through the channel. In 1993, he and Dan Branton initiated a research collaboration with John Kasianowitz at NIST to explore this possibility with the

Conversations with Bangham inspired his research on the role of membranes in the origin of life, and in 1985 Deamer demonstrated that the Murchison carbonaceous meteorite contained lipid-like compounds that could assemble into membranous vesicles.

may be feasible. George Church at
Harvard had independently proposed a similar idea, and Church, Branton and Deamer decided to initiate a patent application which was awarded in 1998. Mark Akeson joined the research effort in 1997, and in 1999 published a paper showing that the hemolysin channel, now

Deamer is also the co-author with science writer
