Cough test
Tissue made with colour indicating binding sites. | |
As I'm out of the biochemistry arena, Is it possible to manufacture, in vitro, some binding sites that change colour when bound?
My logic suggests a virus would need a certain level of infection before coughing starts to help transmission. Coughing into a test tissue would easily capture viral output.
The tissue , if it is possible, would be a surface that has similar or the correct binding site and would cause the virus to try and inject it's take over chemistry. This act, the energy for a colour change, indicating infection.
Once infection is identified, care and help can be given. And of course, interactions can be traced.
A bit on the nose there, [pertinax]

I have no idea whether this is feasible, but it sounds as though it
ought to be. [+] |
|
| |
However, I imagine an unintended side effect. |
|
| |
I imagine mandatory face masks made of this. I imagine
one of
them turning, as might be, a distinctive shade of green in
response to a mild harrumph. |
|
| |
Then I imagine a small knot of people in protective
clothing, their
faces a combination of the early-modern surgical beak-
mask
and the klan hood. |
|
| |
And as I read the words "care and help can be given", I
imagine
this helpful team taking swift care of the green cougher,
whose
frantically kicking legs are visible only for a moment as
they are
bundled away. |

Thanks, [Voice]. But I hate it when I imagine a
counterfactual
dystopia, then check the news and find it's not
counterfactual. |
|
| |
The logic of magical thinking tells me I should therefore imagine
utopiae instead. That's bound to work. |
|
| |
Any tool has a counter productive use, it's just the advancement/growth of humanity in step with it's technology. |
|
| |
What [wjt] said. The first part of it, anyway ... |
|
| |
I was expecting the color change to be too small to be noticeable with the naked eye. |
|
| |
The dollar store has immunochromic pregnancy tests for $1, so this is feasible. |
|
| |
// The dollar store has .... tests for $1 // |
|
| |
Almost like it's possible to deduce some sort of causal relationship there... |
|
| |
You may be the fourth person in the world to use that word. I like it. |
|
| |
Also, a monoclonal antibody that detects SARS-CoV-2 was announced as having been identified a week or two ago, so that could be used. It was expected to initially be expensive to produce, though. |
|

This could be good for telemedicine too: You just hold the
used tissues, or tissues up to the screen for your doctor to
look at and she interprets say a 3 color color code from
the used tissue to be any of 340 different illnesses. Or,
better, software watches the telemedicine session in
realtime, spots the used tissue, and deduces the nature
of the illness from the colors on the tissue, informs the
doctor, and then the doctor switches to asking questions
about that particular illness. |
|
| |
I have calculated colorimetric antibody staining can be
less than 4.3 cents a test, so a pack of ten tissues, with a
binary-tree out of illnesses 4200 deep is just 7*4.3c or
about 30 cents a tissue, a mini-pack of ten tissues mailed
to every HMO client could be just $3.00 excluding postage
and improve telemedicine, and increase its use. |

Also, no runny nose? Just expectorate on the tissue. |
