LOC-systems provide a platform where biochemical assays can be miniaturized, integrated and automated in a simple, portable, fast and cost-efficient way [1]. Acoustophoretic devices are a type of Acoustophoresis separation of bacteria from blood cells for rapid sepsis diagnostics 2018-06-14 Our previous study where 57 blood samples from sepsis patients were processed by acoustophoresis indicated increased RBC sedimentation rate as well as increased platelet activation in some patient 2017-12-07 Acoustophoresis has been utilized successfully in applications including cell cell cycle phase synchronization in mammalian cells 39 and isolation of bacteria in blood from sepsis patients 10 . Acoustophoresis offers active manipulation of microparticles in a fluid, independent of the flow field, and over the past decade, and microchip polymerase chain reaction detection of bacteria from blood for rapid sepsis diagnostics,” Anal. Chem.

The movement of particles or cells by the application of acoustic pressure is commonly referred to as acoustophoresis [ 1 ]. Acoustophoretic separations of particles (or cells) in complex, heterogeneous liquid mixtures (e.g., blood) is an efficient method for sorting particle populations into purified fractions. The acoustophoresis chip design is illustrated in figure 1.

Severe sepsis is defined by dysfunction of one of the major organ systems or unexplained metabolic acidosis. The inflammatory reaction is mediated by the release of cytokines, including tumor necrosis factor-alpha, interleukins, and prostaglandins, from neutrophils and macrophages. Sepsis is a clinical syndrome of life-threatening organ dysfunction caused by a dysregulated response to infection. In septic shock, there is critical reduction in tissue perfusion; acute failure of multiple organs, including the lungs, kidneys, and liver, can occur.

We have previously developed an acoustophoresis-based method to directly extract bacteria from a blood sample for analysis without culture [1]. The EU-funded ACUSEPproject aimed to provide a proof-of-concept for new sepsis diagnostics that can detect very few bacteria in the blood within hours. The objective of ACUSEP was to develop a disposable ready-to-use cartridge enabling rapid analysis of sepsis … Microchannel acoustophoresis does not impact survival or function of microglia, leukocytes or tumor cells (2012) Platelet mitochondrial function in sepsis.
