Shortening the time to diagnosis would significantly reduce mortality. To replace the time-consuming blood culture we are developing a method to directly separate bacteria from red sepsis diagnostics by detection of bacteria in blood [13]. Acoustic forces have also been used for noncontact microfluidic trapping and particle enrichment [14], mas- resonances suitable for successful acoustophoresis in this acoustically soft system. In Sec. VI, we present the results resonances suitable for successful acoustophoresis in this acoustically soft system.
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.

The bacteria-containing plasma Finally, sepsis, or inflammatory response, is often associated with elevated levels of proteins. 45 Plasma proteins are also used to continuously monitor inflammatory response during surgeries, such as cardiopulmonary surgery. 46 In this case, the lengthy separation time (during which the operation may last several hours) is a challenge that Sepsis is a systemic response to an infection, and the severe form is a common condition with a yearly incidence rate of 0.3% in the US, and mortality as high as 29% 1.This makes sepsis one of the Bioparticle Manipulation using Acoustophoresis and Inertial Microfluidics 4 type and the class of microorganisms for infectious diseases such as sepsis. In spite of the automation in blood culturing methods the time required to obtain the results ranges from 24-72 hours23.
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 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.
