Point-of-care system identifies viruses quickly, cheaply


Narrator:       This is Science Today. A point-of-care device that can quickly and cheaply identify viruses is being developed by researchers at the University of California, Irvine, and the Lawrence Livermore National Laboratory. UCI physicist Zuzanna Siwy says hospitals already have an existing technique in place that they can possibly modify. Siwy explains that hospitals count and analyze blood cells using a device that relies on an obstruction of a pore.

Siwy:             Blood cells are a hundred times larger than viruses, so the technique existing in a hospital is not capable of seeing such tiny objects like viruses. So, what we focused on is developing a membrane in a little nano tunnel, which will become an insert to already existing technique called coulter counter technique, which would be simply inserted in it and would be already capable of detecting and identifying a virus which we try to detect.
