Here we describe a colorimetric sensor in which particles composed of phospholipids and polymerized polydiacetylene (PDA) lipids were shown to exhibit striking color changes upon interactions with ...

CCD cameras usually have larger pixels than CMOS cameras. The benefit of larger pixels is more surface area to gather photons ...

Importantly, the new device needed just the tiniest pinprick of blood, would work with blood straight from the body, and could measure glucose levels much more accurately than colorimetric methods.
