The acoustophoresis subsequently translates the beads into a stream of uncoloured buffer in the channel centre (continuous flow bead washing). Washed beads exit via the central outlet.

Free flow acoustophoresis: microfluidic-based mode of particle and cell Zelenin, S. Microfluidic-based isolation of bacteria from whole blood for sepsis

Two of the most common causes of death in the world are cancer and sepsis (blood poisoning). In the U.S. alone, more than 250,000 people die every year as a result of sepsis and more than 500,000 die of cancer. The death rates for both of these diseases are also expected to increase 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. 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.

In SectionVI, we present the results of a more realistic model in three dimensions (3D) of the all-polymer device, and discuss them in relation to preliminary experimental results.

Acoustophoresis sepsis

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]. 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.

Acoustophoresis: the art of combining acoustics and microfluidics The manipulation of particles is an essential feature of Lab-on-a-chip (LOC) devices. LOC-systems provide a platform where biochemical assays can be miniaturized, integrated and automated in a simple, portable, fast and cost-efficient way [1].

In paper IV, elasto-inertial microfluidics where viscoelastic flow enables size-based migration of cells into a non- Newtonian solution, was used to continuously separate bacteria from unprocessed whole blood for sepsis diagnostics.

Some of our currently available technologies include microfluidic platforms for rare cell detection, enumeration and isolation in single-cell format, blood plasma separation by capillarity and acoustophoresis, detection of gasotransmitters, dengue diagnosis and CTC Sweden stands up for open access – cancels agreement with Elsevier LUBcat LIBRIS 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 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].
