Atossa Genetics, Inc. to Ring the Stock Market Closing Bell in Celebration of Recent Listing on NASDAQ Stock Market

NORTHBROOK, IL--(Marketwired - August 22, 2013) - Nanosphere, Inc. (NASDAQ: NSPH), a company enhancing medicine through targeted molecular diagnostics, today announced that it will present data from eight studies at the 53rd Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), September 10-13, 2013, in Denver, CO. Six studies will illustrate the accuracy and reliability of Nanosphere’s Verigene® System in detecting bloodstream infections. A seventh study compares the accuracy of the Verigene System versus the BioFire FilmArray for rapid identification of gram-positive bacteria in blood cultures; and an eighth compares the accuracy of the Verigene System with Meridian BioScience’s Illumigene and Quidel’s AmpliVue for rapid identification of C. difficile in stool.

“We are pleased with the growing body of clinical evidence that demonstrates the sensitivity and specificity of the Verigene System in rapidly and accurately detecting infectious pathogens and drug resistance markers,” said Michael McGarrity, Nanosphere’s president and chief executive officer. “Early and accurate diagnosis, particularly for critical bloodstream and gastrointestinal infections, is vital to healthcare providers for determining the most appropriate course of treatment for their patients.”

About the Verigene® System

The Verigene® System uses core proprietary gold nanoparticle chemistry to offer highly sensitive, highly specific molecular diagnostic results through low-cost multiplexing. The Verigene System rapidly and accurately detects infectious pathogens and drug resistance markers by mapping the genome of a particular bacterium. Currently, Verigene assays target infections of the bloodstream, respiratory tract and gastrointestinal tract. The System also offers additional capabilities in cancer, cardiovascular disease and autoimmune disease. The information gathered from Verigene enables clinicians to identify diseases earlier and make informed patient treatment decisions more quickly, which may result in improved patient outcomes, reduced costs, optimized antibiotic therapy, reduced spread of antibiotic resistance and saved lives.
