In fact, Bayley stayed away from DNA sequencing as a professional courtesy to Branton, making progress in chemically modifying the hemolysin to use it as a single-molecule sensor for drugs, chemicals, and metal ions.

The technique involves creating a lipid bilayer membrane similar to those in living cells, and "drilling" a pore in it with a protein (alpha-hemolysin) produced by the Staphyloccoccus aureus bacteria specifically to penetrate cell membranes.

Because the dimensions of the lipid bilayer and the alpha-hemolysin pore, as well as the required amount of electrical current, are at the nanoscale level, the "single-molecule mass spectrometry" technology may one day be incorporated into "lab-on-a-chip" molecular analyzers and single-strand DNA sequencers.

(A, B1, B2, D), the presence of the hly (hemolysin) gene and the antibiotic resistance pattern, that the E. coli population structure was modified not only by the hydrological conditions (dry versus wet periods, rainfall events), but also by how the watershed was used

The bacterium Staphylococcus aureus, a common cause of infection in humans, secretes a toxin known as alpha-hemolysin that kills human cells by forming holes in their membranes, through which chemicals essential to survival leak out.
