Brain injury diagnosed with a finger prick and an optofluidic chip

Posted by in categories: computing, neuroscience

Researchers in the UK claim to have developed a microfluidic chip that can rapidly tell whether someone has suffered a traumatic brain injury from a finger-prick blood sample. The optofluidic device detects a biomarker linked to brain injury, based on the way that it scatters light (Nat. Biomed. Eng. 10.1038/s41551-019‑0510-4).


An optofluidic device uses Raman spectroscopy to detect a biomarker in blood associated with traumatic brain injury.
