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.

Acoustophoresis is a label-free separation technique where particles exposed to an acoustic standing wave ﬁeld are aﬀected by an acoustic radiation force. A microchannel having a width matched to a half-wavelength of the actuation frequency displays a single pressure node along the …

This loss of precious time used for identification process 2018-06-14 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. Acoustophoresis is a label-free separation technique where particles exposed to an acoustic standing wave ﬁeld are aﬀected by an acoustic radiation force. A microchannel having a width matched to a half-wavelength of the actuation frequency displays a single pressure node along the … Acoustophoresis: the art of combining acoustics and microfluidics.

It is a life-threatening medical emergency. 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 This paper describes an integrated microsystem for rapid separation, enrichment, and detection of bacteria from blood, addressing the unmet clinical need for rapid sepsis diagnostics.

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.

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 Finally, sepsis, or inflammatory response, is often associated with elevated levels of proteins.

Sepsis is a serious infection caused by the invasion of microorganisms into the bloodstream, and mortality due to sepsis accounts for 9.6%–26% of the total deaths in hospitals 1-5.Despite the improvement of diagnostic techniques, the current gold‐standard method—blood culture—has the limitations of a long incubation time (1–7 days) for bacteria identification and a relatively high

Sepsis is an acute and sometimes deadly reaction to an infection, usually caused by bacteria. 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].

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].
