How do you sample blood in a non-invasive way?
Graphene-based biosensors incorporated in arrays of microneedles are emerging as an alternative to hypodermic needles and could be the next generation of blood sampling devices.

Advancements in biosensors and electronics are making real-time disease monitoring and detection easier and safer, with new sensors capable of detecting single biomolecules in complex mixtures a feat that was once unheard of.
For patients with diabetes, creating a non-invasive and long-lasting wearable sensor capable of monitoring blood glucose levels and perhaps even administering insulin based on its readings would replace the need for hypodermic needles, which can be unpleasant, even painful for some.
