Knowing that current methods to detect viruses and other biological markers of disease are effective, yet large and expensive (such as fluorescence microscopes), a team of researchers at the University of Tokyo (Tokyo, Japan) has developed and tested a miniaturized virus-scanning system that makes use of low-cost components and a smartphone. The researchers hope the system could aid those who tackle the spread of diseases faster, as current tools—while highly accurate at counting viruses—are too cumbersome for many situations, especially when rapid diagnosis is required.
The newly developed device, which scans biological samples for real viruses, is portable, low-cost, and battery-powered. Yoshihiro Minagawa from the University of Tokyo, who led the development, tested the device with viruses, but says it could also detect other biological markers.
“I wanted to produce a useful tool for inaccessible or less-affluent communities that can help in the fight against diseases such as influenza,” says Minagawa. “Diagnosis is a critical factor of disease prevention. Our device paves the way for better access to essential diagnostic tools.”
