Zetanostics Inc has the ability to detect Sars-Cov-2 virus using electrochemical methods.

This technology can also be used to detect the virus in water, including wastewater. Excellent method to determine how the disease has spread in the community.
This is the Sars-Cov-2 Virus that causes the respiratory disease Covid-19. Zetanostics has developed technology to detect this with a cell phone!!!
This electrochemical detection technology can be applied to other viruses and also to some bacteria.
The Sars-Cov-2 virus size is about 100 nm dia. Comparable to the Influenza virus.
The Zika virus is about 50 nm.
The virus is about a magnitude smaller than bacteria. E.Coli
E:57 is about 2.5 microns.
Covid‐19 is very sticky. Can stick to stainless steel for about 3
days. It can also survive on airborne particulate matter for days.
Zeta potential ‐30 mV.
