A company is developing a chemical sensor for organic toxic agents. They use a
polymer matrix (PDMS) treated with a carbon mixture to make the polymer
"sticky" to the molecules of interest. To detect the presence of absence of a
chemical on the sticky polymer, an ultraviolet laser illuminates the device and
the resulting fluorescence examined. The company has noticed, however, that
their devices degrade after about 1 week of use. They need to know if the UV
light is causing the underlying polymer to degrade or if the polymer treatment
causes a degradation, and if so, what can be done about it. To find the answer,
they call Fortnight.
Together, the Fortnight
Associate and the client write a
Request describing the client's needs. The Request reads:
 |
A company needs to understand the interaction between coherent UV light and
polymer (PDMS) and polymer treated with carbon. Under what circumstances does
the polymer degrade, what are the failure modes, and what can be done to
minimize the degradation?
|
Leads
sent in response from the Fortnight
Network include:
 |
"I have been working at University ABC in the Chemical Engineering department.
Our research is on polymer-optical interactions. There are several articles I
have read that, with a little more literature review, could provide the basis
for an answer to the client's questions. Effects of this type of polymer
treatment have also been studied. I am not as familiar with them, but I know
where to find the information."
|
 |
"My company is involved in making on-chip biological detection devices for DNA
screening. We use similar processes for detection, although we focus on
substantially different molecules than does the client."
|
 |
"We are a major chemical manufacturer and produce a wide variety of polymers. We
do extensive lifetime testing under numerous conditions. I am not sure if we
can be of service in this case, but we may be able to help. In fact, we would
be interested in learning the answer, too."
|
The client is most interested in having the university researcher look into what
has been reported in the literature and, through contacts with the client,
writing up a summary of the most likely effects responsible for the polymer
degradation. The client also wishes to talk in more detail with the on-chip
biological detection company if they are not a potential competitor.
Fortnight looks into the background of this potential
Solution Provider and, after getting their permission, releases their
name to the client to see if they feel comfortable speaking directly with one
another. All the
Experts whose
Leads were presented to the client are rewarded, and the two whose
Leads the client decided to pursue are additionally compensated a substantial
amount after working with the client.
DISCLAIMER: This is a contrived example.
Any semblance to any existing company or problem is merely coincidental.
