Early detection device for coal

A hand-held device that can detect the presence of anthrax bacteria within one hour from a sample containing about 40 micro spores can soon detect the germ of the disease, according to the scientists. from Albany and Cornel.

The device is designed to be small enough to fit into the carry-on luggage of passengers on board. It is capable of detecting many other pathogens, such as Salmonella (a bacterium that makes food toxic) or can be used in DNA forensics.

The scientists took seven years to design and complete this handset. The device is capable of restoring, collecting and purifying DNA from the original sample, then performing a gene amplification (PCR) to determine if anthrax is present. Genetic amplification can amplify a very small amount of DNA and is also the basis for the detection of biological material.

In addition to detecting Coal, the device is also used to investigate crimes. If detectives want to find criminal evidence, the device can help them quickly determine the sex or eye color of the suspect.
