Field tool Freedom4 can detect viruses and bacteria in samples.
Researchers at Otago University in New Zealand have unveiled Freedom4, a battery-powered, handheld device that can detect viruses and bacteria in samples in real-time. The device is also able to identify the level of infection.
Freedom4 uses a technology known as quantitative polymerase chain reaction, which amplifies a targeted DNA molecule so that it can be detected. Originally developed in 1983, the process uses a limited number of copies of DNA and generates up to several million copies so that…
