This method has proven to be useful in sepsis diagnosis due to the quick turnaround time and possibly for blood disinfection given that it can be scaled-up to handle larger volumes. In a recent example [ 22 ], bulk acoustophoresis was used to separate bacteria from the blood cells from whole blood samples.
Developing a fast and continuous monitoring device for SIRS detection will bring a huge breakthrough in clinical world for sepsis diagnosis. Platform was used at Apollo Hospitals, Chennai (our collaborator) for two months (March- April 2018) as part of a pilot study to detect the H2S level in ICU patients before, during and after surgery.

KEYWORDS: Acoustophoresis, Bacteria, Blood, Sepsis INTRODUCTION Sepsis is a systematic response to infection, most often by bacteria. It is the 10th most common cause of death in the US, but the mortality can be decreased drastically by fast antimicrobial treatment [1,2]. The standard method to identify It is defined as a microbial invasion and excessive immune reaction. There is no common cure for sepsis, and mortality in sepsis is high and rises quickly, so it is important to start precise treatment quickly. 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.

We present a significantly improved acoustophoresis method to separate bacteria from red and white blood cells. As much as 98% of the bacteria were recovered, while only 0.06 % of the red and white blood cells remained.

Sepsis is a life‐threatening condition that leads to numerous deaths, and its treatment is very expensive. 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.
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. The bacteria-containing plasma proceeds to a glass capillary with a localized acoustic standing wave field where the bacteria are trapped onto suspended polystyrene particles. Sepsis is a common and often deadly systemic response to an infection, usually caused by bacteria. The gold standard for finding the causing pathogen in a blood sample is blood culture, which may take hours to days. Shortening the time to diagnosis would significantly reduce mortality. To replace th … Sepsis is a common and often deadly systemic response to an infection, usually caused by bacteria.
