Real-time detector for intravenously delivered drugs

http://phys.org/news/2013-09-real-time-detector-iv-drugs-life-threatening.html

A University of Illinois developed optical device can identify fluid in an IV line in real-time, improving the safety of delivery.  Professor Brian T. Cunningham and his team used Surface-Enhanced Raman Scattering (SERS) technology, a powerful analytical tool prized for its extreme sensitivity in obtaining molecular signals that can be used to identify chemicals. To determine the identity of a particular IV medication, researchers shine laser light onto a nanostructured gold surface that contains millions of tiny “nano-domes” that are separated from each other by as little as 10 nanometers.  The nano-domes are incorporated into the inner surface of IV tubing, where they are exposed to drugs that are dispersed in liquid. They capture the light scattered from drug molecules that are in contact with the nano-domes and use SERS to determine the drug’s molecular signature. Finally, they match the signature to known signatures for the drug in order to confirm the presence of a specific medication in the IV line.

    My developer is trying to persuade me to move to
    .net from PHP. I have always disliked the idea because of the costs.
    But he’s tryiong none the less. I’ve been using Movable-type on a number of websites for
    about a year and am concerned about switching to another platform.
    I have heard very good things about blogengine.net. Is there a way I can import all my wordpress posts
    into it? Any kind of help would be greatly appreciated!

    Howdy would you mind stating which blog platform you’re working with?
    I’m planning to start my own blog in the near future but I’m having a hard time choosing between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design and style seems different
    then most blogs and I’m looking for something
    completely unique. P.S My apologies for
    getting off-topic but I had to ask!

  21. Foster

    a look for. You have ended my 4 day lengthy hunt!
    God Bless you man. Have a nice day. Bye

  22. Lonnie

    Hmm it looks like your website ate my first
    comment (it was super long) so I guess I’ll just sum it up what I submitted
    and say, I’m thoroughly enjoying your blog. I as well am an aspiring blog blogger but I’m still new to everything.

    Do you have any suggestions for novice blog writers?
    I’d certainly appreciate it.

  23. Belle

    Howdy! I realize this is sort of off-topic however I
    needed to ask. Does building a well-established blog like yours require a large amount of
    work? I’m completely new to blogging but I do write in my
    diary everyday. I’d like to start a blog so I can share my personal experience and views online.
    Please let me know if you have any kind of recommendations or tips for brand new
    aspiring bloggers. Thankyou!
