A new biosensor has been developed that allows researchers to track oxygen levels in real time in “organ-on-a-chip” systems, according to North Carolina State University. The organ-on-a-chip makes it possible to ensure that bodily systems more closely mimic the function of real organs. The goal is to use these organs-on-a-chip to expedite drug testing and development by evaluating the effectiveness of new drugs with small-scale, biological structures that mimic a specific organ function, such as transferring oxygen from the air into the bloodstream in the same way that a lung does.

From Silk to Sensors

The India-based Achira Labs has taken silk screening to a whole new level.

Chemical engineers from Achira Labs have found a way to weave diabetes test strips from silk, rather than the conventional plastic or paper.

But they’re not creating these strips for luxury. Silk would actually have several advantages in a country such as India, where weavers are abundant and silk is inexpensive.

Achira Labs have used these silk sensors before to detect other medical issues, including strips that change color when they detect a deadly type of diarrhea in diapers.

These new silk strips for diabetics are not only just as efficient as other types of glucose strips, they are also easier to manufacture.
