Acoustofluidic separation enables early diagnosis of traumatic brain injury based on circulating exosomes.

ABSTRACT: Traumatic brain injury (TBI) is a global cause of morbidity and mortality. Initial management and risk stratification of patients with TBI is made difficult by the relative insensitivity of screening radiographic studies as well as by the absence of a widely available, noninvasive diagnostic biomarker. In particular, a blood-based biomarker assay could provide a quick and minimally invasive process to stratify risk and guide early management strategies in patients with mild TBI (mTBI). Analysis of circulating exosomes allows the potential for rapid and specific identification of tissue injury. By applying acoustofluidic exosome separation-which uses a combination of microfluidics and acoustics to separate bioparticles based on differences in size and acoustic properties-we successfully iso
