Quick and accurate COVID-19 testing is a key part of getting the pandemic under control. And a Laramie company is part of the effort to make that a reality. Wyoming Public Radio s Ivy Engel talked to CellDrop Biosciences founder, Ben Noren, about the type of testing they are developing.
Ben Noren: We use materials called hydrogels. So if you think of jello, it s probably the most ubiquitous example of a hydrogel. Hydrogels make up a lot of what s in your body and so using synthetic hydrogels, we re able to recreate things like the spaces that cells live inside of you. This particular project was based out of using hydrogel like a sponge and taking these, what s called lateral flow amino assay tests, which basically detect various biological substances in a sample like saliva, but doing it in a way that works better than what existed. Because unlike existing tests, we could build these hydrogel structures at very, very small length scales, dehydrate them, and when we put a s
Researchers in South Korea have successfully developed a wearable sensor that can detect illegal drugs in sweat by using nanomaterials technology that amplify the optical signal of narcotics to a flexible, body-worn material.
The technology enables fast and highly sensitive drug detection: the sweat patch is attached to the skin for a certain period of time and then irradiated with light for testing. It only takes one minute without requiring additional process.
