NPR ran this story recently, about a new material with which diabetic test strips can be made:
Weavers Turn Silk Into Diabetes Test Strips
I have to admit, this is intriguing -- not just because the silk strips are cheaper than plastic or paper to make, but because I wonder if it means anything new for the product and, overall, the industry. I think there would be some concerns here, though, if people are opposed to using silk for ethical reasons.
I think the ethical concerns are valid, since silk production requires killing the silkworms in order to make it. I don't normally think about it, but then again I have owned very little silk in my life. I feel like I would have to consider the issue and take a stand on one side or the other if the company that makes my meter and test strips started using silk.
Also, the strips may be cheaper now, but would that change if all the strip companies started using silk, and there was too great a demand for it?
