The BBC yesterday published a great article on how researchers in the US have hugely boosted the sensitivity of a widespread imaging and sensing technique, using just an off-the-shelf DVD.
At Handisc we are big fans of the physical disc and now scientists are jumping on board. In brief, Fluorescence spectroscopy is used to diagnose disease, image inside cells or detect toxins, unfortunately the signals are weak, but thanks to a report in Nanotechnology, it has outlined how to boost those signals, by utilising the ready made pits and grooves of a DVD.
To read the report in full go to http://www.bbc.co.uk/news/science-environment-20338540 or to sit in wonder of a DVD, why not pop along to our shop http://shop.handisc.co.uk/and buy a spindle for yourself. Who knows what else the DVD is capable of.
The method benefits from what began as imperfections in the production process
