the unmet clinical need for rapid sepsis diagnostics. The blood sample is first processed in an acoustophoresis chip, where red blood cells are focused to the center of the channel by an acoustic standing wave and 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-causing organisms directly from suspected blood samples. Acoustophoresis, as an alternative microfluidic cell handling technique, offers a label-free and continuous cell separation that provides both high throughput and good separation performance for Final Report Summary - ACUSEP (Integrated whole blood acoustophoresis and homogeneous nucleic acid detection cartridge for rapid sepsis diagnostics) Executive Summary: The aim of the ACUSEP project was to provide a proof-of-concept of a new method for sepsis diagnostics that would enable the identification of sepsis causing bacterium directly from a blood sample within a couple of hours. The blood sample is first processed in an acoustophoresis chip, where red blood cells are focused to the center of the channel by an acoustic standing wave and sequentially removed.
Therefore, it is important to develop a system that accurately isolates and enriches bacteria in blood without contamination. In this study, we developed a system in which sepsis‐related bacteria are continuously isolated using DEP forces. 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.

Identifying the bacteria by blood culture often takes several days, which may be too long to save the patient. We have previously developed an acoustophoresis-based method to directly extract bacteria from a blood sample for analysis without culture [1]. Acoustophoresis separation of bacteria from blood cells for rapid sepsis diagnostics Acoustophoresis, the ability to acoustically manipulate particles and cells inside a microfluidic channel, is a critical enabling technology for cell-sorting applications. However, one of the major impediments for routine use of acoustophoresis at clinical laboratory has been the reliance on the inherent physical properties of cells for separation.

Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death. Almost any type of infection can lead to sepsis. Sepsis is a serious infection that causes your immune system to attack your body. As a result of that attack, septic shock can occur and result in death. Read on to learn about the three stages of

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. 88,
Sepsis is, however, hard to diagnose, as it has no symptoms specific to it alone, and thus new ways to diagnose sepsis and its The objective of ACUSEP was to develop a disposable ready-to-use cartridge enabling rapid analysis of sepsis-causing organisms directly from suspected blood samples. To achieve this, scientists used the microfluidic method of acoustophoresis to collect bacteria by ultrasonic sound waves in a small sample.
