LAMP Malaria Assay Evaluated in Non-Endemic Setting

Imported malaria infections in non-endemic regions remain common due to increasing travel to endemic malaria areas and population movements. Yearly approximately 10,000 cases of imported malaria are reported, but the actual number may be as high as 30,000. More...

Image: The system uses a commercial smartphone to acquire and interpret real-time images of an enzymatic amplification reaction that takes place in a silicon microfluidic chip that generates green fluorescence and displays a visual read-out of the test. The system is composed of an unmodified smartphone and a portable 3-dimensional-printed cradle that supports the optical and electrical components, and interfaces with the rear-facing camera of the smartphone (Photo courtesy of the Micro & Nanotechnology Laboratory, University of Illinois at Urbana-Champaign).

Potential Uses for Smartphone-Based Diagnostic Tool Described

Two recent papers described potential applications for a smartphone-based instrument that can evaluate biological samples with the accuracy of clinical laboratory analyzers but at a fraction of the cost. More...

Lipid Vesicles Replace Blood in New Bacteria Test

Beta-hemolytic bacteria are those pathogens that are frequently to blame for illnesses that are spread among school children like Streptococcus, or those like Listeria that cause many foodborne illnesses. The current test involves streaking a patient sample onto blood agar plates. More...
