  • 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.

  • 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. - Articles related to Scientists uncover mysterious workings of cholera bacteria
