Quantitative lateral flow
The interesting article by Bethany Halford on lateral flow tests (C&EN Sept. 19, 2022, page 6) inspired me to express it in the following poem.
A current technique that is all on the go,
That gives a rapid test, is lateral flow
But results, so far, have all been
Now the Swager group has made it
Without using sophisticated
As a simple smartphone is used on this
They used particles with conducting
With glucose oxidase enzyme attached to
them as well.
So, when glucose is present hydrogen
peroxide is released
And the conductivity of the polypyrrole is
An attached rfid tag detects this change
And transmits the info to a smartphone
Thus allowing the glucose concentration to
And transmitted to a lab and the information
This technique can be used with other
Allowing more health care information to be
sent, for starters.
So we salute Tim Swager, Jie Li, Weize Yuan
For this advance in instrumentation and we
want all to know.
