A suitcase-sized device to detect anthrax, which normally requires a full-sized lab and take days to detect, has been developed by researchers at Cornell University.
Anthrax is an infectious disease due to a type of bacteria called Bacillus anthracis and it affects both humans and other animals. Infection in humans most often involves the skin, gastrointestinal tract, or lungs.

It integrates sample purification and real-time DNA analysis chambers as well.
The detector only needs a small biological sample. Insert the sample and the machine automatically picks up cells and separates the DNA, which is then analysed in real-time.
With this system, tests can be done in the field more quickly and easily, and the inventors claim it can detect anthrax even if only a few dozen spores are present.
The discovery was published in the International Journal of Biomedical Nanoscience and Nanotechnology.
