Blu-ray Discs and Players Used for Massive Pathogen Screening
http://cdn.medgadget.com/wp-content/uploads/2014/03/bluray-detector.jpg
Blu-ray discs are great for watching ******, but the tech**logy within them and the players that spin them has been harnessed for pathogen detection by a team of Spanish scientists. The Blu-ray discs had a layer of microarrays applied to their surface where antibody reactions and signal amplification takes place. The discs were then placed into a Blu-ray player, the laser of which was used to measure the optical properties of each **de within the microarrays that correlated to a successful reaction or **t.
The team tested the system for detection of*Cro**bacter sakazakii, a GI parasite, and*Salmonella typhimurium.*They report in journal Biosensors and Bioelectronics that the system provides “similar sensitivity as real-time quantitative PCR.”*Because each **de can run a unique test, the system provides the ability to screen large numbers of people rapidly and with essentially already existing tech**logy.
From the study abstract:
BDs preserve the optical properties according to Blu-ray specifications, ensuring maximum accuracy and sensitivity of the drive during disc scanning. Detection limits of 0.4*g/L for microcystin LR and 100*and 101*cfu/mL for*Salmonella typhimurium*and*Cro**bacter sakazakii*respectively, were achieved, improving considerably the DVD performances and reaching similar sensitivity as real-time quantitative PCR. Blu-ray tech**logy adapted to the analysis of high density arrays highlights the e**rmous capabilities (high sensitivity, speed-scanning, optical resolution, portability) for point-of-care settings, diag**stics, and high-throughput screening applications.
