Investigators at the University of Trás-os-Montes and Alto Douro have come up with a rapid way of testing for Covid-19 using technology that identifies grape varieties for the production of wine.
The procedure “guarantees results in 20 minutes” and does not require specialised personnel to perform it nor expensive reagents.
Say reports, the test – developed under the WineBioCode patent – should be ready for use by the end of February.
It involves a ‘biosensor composed by nanoparticles that are Covid specific sequences. Using sequences also used for PCR tests as probes we were able to identify the virus”, investigator Paula Martins Lopes has told Rádio Renascença.
The only ‘issue here’ is that the PCR tests have been proven to be unreliable in testing for live viruses (click here), although authorities continue to use them. As technical reports explain they can detect genetic sequences of viruses, but not viruses themselves. That in some degree explains the vast numbers of people sent into isolation while showing zero symptoms (the most recent high-profile example of this is Portugal’s own president, Marcelo Rebelo de Sousa click here).
