MICROFLUIDIC VISCOMETER BY ACOUSTIC STREAMING TRANSDUCERS
The measurement of fluids viscosity represents a huge need for many biomedical and material applications. Sample fluids containing DNA, antibodies, proteins, and even cells have become important therapeutical options. The physical properties, including viscosity, of these biologics are critical factors in the optimization of the biomanufacturing processes. Here we demonstrate an acoustic microstreaming platform that induces fluid transport from second-order microstreaming. We validate our platform with water-glycerol mixture to reflect different viscosities and measure the maximum speed of the second-order acoustic microstreaming within seconds. Our demonstrated platform does not require external instruments to pump fluids and consumes small amount of fluid sample (< 10 uL) and is easy to incorporate with automation systems.

Knowledge of rheological properties, such as viscosity and elasticity, is necessary for efficient material processing and transportation as well as biological analysis. Existing rheometers operate with large sample volume and induce sample contact with container or device walls, which are inadequate for rheological analysis of sensitive fluids limited in availability. In this work, we introduce acoustic tweezing spectroscopy (ATS), a novel noncontact rheological technique that operates with a single 4–6 μl drop of fluid sample. In ATS, a sample drop is acoustically levitated and then exposed to a modulated acoustic signal to induce its forced oscillation. The time-dependent sample viscosity and elasticity are measured from the resulting drop response. The ATS measurements of polymeric solutions (dextran, xanthan gum, gelatin) agree well with previously reported data. The ATS predicts that the shear viscosity of blood plasma increases from 1.5 cP at 1.5 min of coagulation onset to 3.35 cP at 9 min, while its shear elastic modulus grows from a negligible value to 10.7 Pa between 3.5 min and 6.5 min. Coagulation increases whole blood viscosity from 5.4 cP to 20.7 cP and elasticity from 0.1 Pa to 19.2 Pa at 15 min. In summary, ATS provides the opportunity for sensitive small-volume rheological analysis in biomedical research and medical, pharmaceutical, and chemical industries.more » « less

Microstreaming of acoustically excited bubbles presents great potential to mitigate fouling for membrane technologies. However, the acoustic streaming in bulk fluids under membrane separation conditions is not well explored. In this work, we investigate the microstreaming of 3D printed Helmholtz-like bubble-trapping structures (BTSs) under no flow, pressurized, and crossflow conditions that are relevant to membrane applications. Trapped bubbles are shown to generate formidable microstreaming that spans millimeter distances with velocity as high as 125 mm/s in a bulk aqueous medium. However, complex mode shapes of the bubble oscillation and bubble growth were observed during the frequency sweep. As a result, the streaming velocity decreases by 76% over 30 min, under single frequency excitation. The BTS displayed effective microstreaming under hydrostatic pressure up to 9.0 kPa, and under a crossflow velocity up to 0.2 mm/s, where the microstreaming zone reduced to <1 mm. The results provide the operation window, as well as challenges, for future integration of the BTS into bulk membrane separation processes.more » « less

Abstract. Geological carbon sequestration provides permanentCO2 storage to mitigate the current high concentration of CO2 inthe atmosphere. CO2 mineralization in basalts has been proven to be oneof the most secure storage options. For successful implementation and futureimprovements of this technology, the time-dependent deformation behavior ofreservoir rocks in the presence of reactive fluids needs to be studied indetail. We conducted load-stepping creep experiments on basalts from theCarbFix site (Iceland) under several pore fluid conditions (dry,H2O saturated and H2O + CO2 saturated) at temperature,T≈80 ∘C and effective pressure, Peff=50 MPa,during which we collected mechanical, acoustic and pore fluid chemistrydata. We observed transient creep at stresses as low as 11 % of thefailure strength. Acoustic emissions (AEs) correlated strongly with strainaccumulation, indicating that the creep deformation was a brittle process inagreement with microstructural observations. The rate and magnitude of AEswere higher in fluid-saturated experiments than in dry conditions. We inferthat the predominant mechanism governing creep deformation is time- andstress-dependent subcritical dilatant cracking. Our results suggest thatthe presence of aqueous fluids exerts first-order control on creepdeformation of basaltic rocks, while the composition of the fluids playsonly a secondary role under the studied conditions.more » « less

We report a label-free acoustic microfluidic method to confine single, cilia-driven swimming cells in space without limiting their rotational degrees of freedom. Our platform integrates a surface acoustic wave (SAW) actuator and bulk acoustic wave (BAW) trapping array to enable multiplexed analysis with high spatial resolution and trapping forces that are strong enough to hold individual microswimmers. The hybrid BAW/SAW acoustic tweezers employ high-efficiency mode conversion to achieve submicron image resolution while compensating for parasitic system losses to immersion oil in contact with the microfluidic chip. We use the platform to quantify cilia and cell body motion for wildtype biciliate cells, investigating effects of environmental variables like temperature and viscosity on ciliary beating, synchronization, and three-dimensional helical swimming. We confirm and expand upon the existing understanding of these phenomena, for example determining that increasing viscosity promotes asynchronous beating. Motile cilia are subcellular organelles that propel microorganisms or direct fluid and particulate flow. Thus, cilia are critical to cell survival and human health. The unicellular algaChlamydomonas reinhardtiiis widely used to investigate the mechanisms underlying ciliary beating and coordination. However, freely swimming cells are difficult to image with sufficient resolution to capture cilia motion, necessitating that the cell body be held during experiments. Acoustic confinement is a compelling alternative to use of a micropipette, or to magnetic, electrical, and optical trapping that may modify the cells and affect their behavior. Beyond establishing our approach to studying microswimmers, we demonstrate a unique ability to mechanically perturb cells via rapid acoustic positioning.more » « less
