Eh a lot of “these particles bonded with glucose - so now we can measure blood sugar levels” that’s a massive stretch from where they are at. It’s cool, but no

Eh a lot of “these particles bonded with glucose - so now we can measure blood sugar levels” that’s a massive stretch from where they are at.
It’s cool, but nothing close to what’s described.
- rsfern 3y agoI don’t think the magnetic particles interact with the glucose, they’re just a magnetic transducer basically. The main measurement device is a hydrogel that reacts with the glucose and swells, and they measure how far the magnetic particles move using a magnetometer to sense the change in field strength and back out the concentration (and pH) The linked Nature Comm paper seems pretty thorough, and they are reporting really high sensitivity (1000x what you’d need for typical blood glucose levels) https://doi.org/10.1038/s41467-024-47073-2 https://doi.org/10.1038/s41467-024-47073-2
- lettergram 3y agoOkay sure, I shortened it a bit. My point is the discovery wasn’t directly related to the claims. Your description is more apt than the hyperbole in use cases. To accomplish what they describe would need a lot more research
- rsfern 3y agoTo be fair, they do call it a “proof of concept study” in the press release
