Wisconsin Researchers Create Nano-Bio-Circuits

Posted by timothy on from the invasion-of-the-cheese-menace dept.

opencity writes "A team of scientists at UW-Madison has successfully used single bacterial cells to make tiny bio-electronic circuits. Slipping between the electrodes, the microbes, in effect, become electrical "junctions," giving researchers the ability to capture, interrogate and release bacterial cells one by one. Built into a sensor, such a capability would enable real-time detection of dangerous biological agents, including anthrax and other microbial pathogens. Two mpegs -- 11MB and 35MB -- available here. Related by scale and buzzwords: physorg.com reports scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to sneak nano-sized probes inside cell nuclei, where they can track life's fundamental processes, such as DNA repair, for hours on end. Related cool pictures and strange font choices on Nano-Bio Interface Center."

      Since http isn't a valid toplevel domain name, mozilla style browsers do a google search on http. Then it jumps to the first result which happens to be microsoft.com .

      If you wish to turn this off and be informed that the URL isn't valid rather than a Verisign-style "no domain is invalid" result, go into about:config and search for "keyword", then change keyword.enabled to false.

    Ironically, under Firefox the link forwards to Microsoft.

    Old technology, modern implementation.
    Trouble is, microbes and bacteria vary hugely in size and shape, and may break and divide. Bits may stick, dust and foreign bodies get jammed in the works.If the gates are so narrow, wonder if they bend, or current electroylsis corrodes one terminal over time? Same as a chicken egg size sorter, only smaller, and without light detection circuitry.

    Disposable filter paper, or a roll of filter paper, works, and is cheap, as are glass needletips. A scanning electron microscope does a similar job, but too big to be portable.

    No, for that effect you have to drink it.
