  1. this isn't all that new... by kootch · · Score: 2

    I remember searching EPA's web site a year or two ago, and seeing descriptions of gadgets that they were building that do the same thing as this bioanalyzer and more. They had gadgets that you could put a small amount of pond water in it and it would list all the known contaminants that were in the sample, they had ones that could test a few drops of blood for known diseases as well as do white blood cell counts, and tons of other little kewl gadgets.

    There's a huge trend to take all the giant machines that scientists and doctors need for analysis and shrink them down into handhelds... this one by HP is nothing more than just another one that's hitting the market... except that it's backed by HP and has a small flash animation on its site.

    Oh well.

  2. Micro-labs by upstateguy · · Score: 3

    As a molecular geneticist who's actually used some of these types of devices (like Affymetrix's GeneChip analyzer...with an amazing HP laser scanner www.affymetrix.com), they are nothing short of amazing. The engineering problems are not so much the mechanical (designing silicon surfaces, circuits, etc.) but biological (i.e. the proteins, DNA, cell gunk get in the way, clog those micro-channels or the flouresent tags used in detection have to be so far apart to avoid misreads). Also, you need a REALLY high confidence level for the data they generate. Still, they are a marvel in the way that diagnostics will be able to utilize the load of information from all the genome sequencing projects. These devices are also planned for use as "biosensors" to be used as fast screening methods for biological terrorism (right now any idiot on earth can clog up tons of local, state and federal agencies by sending a fake anthrax warning out). And a tidy sum of money is being made available to make devices like this available (for example, today's announcement by the CDC to give another $40 million in grants for anti-bioterrorism efforts--http://dailynews.yahoo.com/h/nm/19990915/ hl/bio10_1.html).
