New Tool Detects Viruses Quickly and Easily

Researchers at Boston University have developed a biosensor that can detect viruses via blood sample. The machine is very small, about the size of a quarter, and works by using plasmonic nanohole arrays. When a live virus is in the sample, a shift in the resonance frequency of light transmitted through the nanoholes can be detected. The biosensor is able to test for several viruses at once as well as the intensity of the infection. This technology could be put into use in airports in countries where outbreaks of diseases such as ebola are prominent and could prevent the passing of dangerous conditions from one area of the world to another. The sensor works quickly and does not require sample preparation which makes it even more appealing. The researchers are now working on a design that would be practical for use in the field by those with minimal training.

I found this article interesting because it may impact so many individuals in the future and actually prevent the spread of some contagious diseases. I have always heard rumor of tiny sensors being created that would quickly detect diseases (although I always heard about saliva being used). It is really cool to see a similar device becoming a reality.
