New Biosensing Data Have Been Reported by Investigators at IIT (Nanopore Biosensor for Label-Free and Real-Time Detection of Anthrax Lethal Factor)

July 2, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Fresh data on Biosensing are presented in a new report. According to news reporting originating from Chicago, Illinois, by NewsRx correspondents, research stated, "We report a label-free real-time nanopore sensing method for the detection of anthrax lethal factor, a component of the anthrax toxin, by using a complementary single-stranded DNA as a molecular probe."

Our news editors obtained a quote from the research from IIT, "The method is rapid and sensitive: sub-nanomolar concentrations of the target anthrax lethal factor DNA could be detected in similar to 1 min. Further, our method is selective, which can differentiate the target DNA from other single-stranded DNA molecules at the single-base resolution."

According to the news editors, the research concluded: "This sequence-specific detection approach should find useful application in the development of nanopore sensors for the detection of other pathogens."
