Non-contact acoustic capture of microparticles from small plasma volumes.
(2015) In Lab on a Chip 15(12). p.2588-2596- Abstract
- Microparticles (MP) are small (100-1000 nm) membrane vesicles shed by cells as a response to activation, stress or apoptosis. Platelet-derived MP (PMP) has been shown to reflect the pathophysiological processes of a range of cardiovascular diseases and there is a potential clinical value in using PMPs as biomarkers, as well as a need to better understand the biology of these vesicles. The current method for isolating MP depends on differential centrifugation steps, which require relatively large sample volumes and have been shown to compromise the integrity and composition of the MP population. We present a novel method for rapid, non-contact capture of PMP in minute sample volumes based on a microscale acoustic standing wave technology.... (More)

The current method for isolating MP depends on differential centrifugation steps, which require relatively large sample volumes and have been shown to compromise the integrity and composition of the MP population. We present a novel method for rapid, non-contact capture of PMP in minute sample volumes based on a microscale acoustic standing wave technology. Capture of PMPs from plasma is shown by scanning electron microscopy and flow cytometry. Furthermore, the system is characterized with regards to plasma sample concentration and flow rate. Finally, the technique is compared to a standard differential centrifugation protocol using samples from both healthy controls and ST-elevation myocardial infarction (STEMI) patient samples. The acoustic system is shown to offer a quick and automated setup for extracting microparticles from small sample volumes with higher recovery than a standard differential centrifugation protocol.
