New Gold Nanoparticles Study Findings Have Been Reported by N.M.M. Pires and Co-Researchers (Ultrasensitive opto-microfluidic immunosensor integrating gold nanoparticle-enhanced chemiluminescence and highly stable organic photodetector)

By a News Reporter-Staff News Editor at Biotech Week -- Investigators publish new report on Gold Nanoparticles. According to news reporting originating from Tonsberg, Norway, by NewsRx correspondents, research stated, "The expensive fabrication of current opto-microfluidic sensors is a barrier to the successful adoption of these devices in point-of-care testing. This work reports a simple inexpensive opto-microfluidic device incorporating a poly(dimethylsiloxane)-glass hybrid microfluidic chip modified with gold nanoparticles and a high-detectivity, high-stability organic photodetector."

Our news editors obtained a quote from the research, "The enhancing effect of the gold nanoparticles on horseradish peroxidase-luminol-H2O2 chemiluminescence was exploited in rapid single-analyte immunoassays. The limit of detection for 17-beta estradiol was 2.5 pg/ml, which is similar to 200 times more sensitive than previously reported chemiluminescent immunosensors employing other organic photodetectors."

According to the news editors, the research concluded: "Detection was also demonstrated in complex media, including natural water and blood serum."
