Technical University Details Findings in Engineering

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Engineering have been published. According to news reporting out of Valencia, Spain, by NewsRx editors, research stated, "The potential and the capabilities of Blu-ray technology (discs and drives) for massive screening applications are presented. High density microarrays are fabricated onto a Blu-ray disc and applied for the determination of microcystin residues and pathogenic microorganisms."

Our news journalists obtained a quote from the research from Technical University, "Specific probes were physisorbed onto the BD surface and the biorecognition event was displayed using labeled secondary antibody solution and subsequent signal amplification. The attenuation of the reflected light caused by the reaction product is detected by the Blu-ray drive and inversely correlated with analyte concentration. 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 10(0) and 10(1) cfu/mL for Salmonella typhimurium and Cronobacter sakazakii respectively, were achieved, improving considerably the DVD performances and reaching similar sensitivity as real-time quantitative PCR."

According to the news editors, the research concluded: "Blu-ray technology adapted to the analysis of high density arrays highlights the enormous capabilities (high sensitivity, speed-scanning, optical resolution, portability) for point-of-care settings, diagnostics, and high-throughput screening applications."
