Working From Home - Impacts of Coronavirus

<< < (245/447) > >>

PlainName:
Here in the UK we didn't do a lockdown but were asked to be sensible in doing social distancing. The result? We have the highest numbers of deaths in Europe and had to have an enforced lockdown. The simple fact is that people en mass are dicks and will do whatever the hell they want if not forced to do something else. Just look at how quickly the rule of law breaks down when there's a disaster - Katrina, for instance. So whilst lockdowns to combat the virus may not be necessary and we could do it gently and sensibly in theory, they are essential just to get down to even those 40% you mention.

Where are the FET COVID-19 biosensor meters?

(which give instant testing results, and could make it possible to ramp up the amount of testing)

No such thing as instant testing results. Even the article only claims rapid testing. The "> 1 min" result time in that last chart doesn't inspire confidence...there's a LOT of room above 1 minute. ("instantaneous measurement" when used by scientists refers to data at a particular point in time, not how fast it takes to produce/process that data.)

In any case, technology takes time and engineering to move from a lab to prototypes that can be used in the real world. And assuming that's successful, a lot more time to produce in sufficient numbers to have any real effect. In normal conditions, we're typically talking years. Even in pandemic conditions with a blank check and assuming the science isn't flawed, ramping up production, quality control and distribution won't happen overnight. (If the science was tested enough to justify a blank check from some government, we'd probably be hearing about it by now.)

Might even be able to turn this technology into a Covid breathalyzer?

Thank you!

"The company is currently targeting two main applications: early detection of Lyme disease and cancer detection. Graphene Frontiers will first enter the research-use-only (RUO) market with a basic, customizable product. This is a limited volume market (orders may reach a few hundreds of chips), but later on they want to also enter the diagnostic and consumer health markets - which may require tens of millions of chips.

In the first stage, the company aims to produce those GFET-based sensors on 4" wafers in low-volume (few wafers per day) in-house. The chip itself is about 5x5 mm in size, and will come in multiplex/array of about 10 devices. Each chip is expected to cost a "few dollars". Later in 2014 they will partner with a MEMS fab for mass-scale 4" wafer production. By 2015, they plan to be able to produce tens of millions of chips per year."

So it was supposed to be quite affordable at that stage, a few years ago.



Presumably this kind of meter is how they propose to do something like analyzing feces in the sewer system for COVID-19, presumably to gather aggregate data on peoples health status .

Instant testing would allow them to focus more on the aspects of the COVID-19 situation that could make it less of a problem now. (like better, inexpensive diagnosis and treatments, in this case, instant testing that could get people into treatment earlier.)
