High-Throughput Microfluidic Characterization of Erythrocyte Shapes and Mechanical Variability.

ABSTRACT: The motion of red blood cells (RBCs) in microchannels is important for microvascular blood flow and biomedical applications such as blood analysis in microfluidics. The current understanding of the complexity of RBC shapes and dynamics in microchannels is mainly based on several simulation studies, but there are a few systematic experimental investigations. Here, we present a combined study that systematically characterizes RBC behavior for a wide range of flow rates and channel sizes. Even though simulations and experiments generally show good agreement, experimental observations demonstrate that there is no single well-defined RBC state for fixed flow conditions but rather a broad distribution of states. This result can be attributed to the inherent variability in RBC mechanical properties, which is confirmed by a model that takes the variation in RBC shear elasticity into account. This represents a significant step toward a quantitative connection between RBC behavior in microfluidic devices and their mechanical properties, which is essential for a high-throughput characterization of diseased cells.

Project description:Magnetic nanoparticles (MNPs) are useful for many biomedical applications, but it is challenging to synthetically produce them in large numbers with uniform properties and surface functionalization. Magnetotactic bacteria (MTB) produce magnetosomes with homogenous sizes, shapes, and magnetic properties. Consequently, there is interest in using MTB as biological factories for MNP production. Nonetheless, MTB can only be grown to low yields, and wild-type strains produce low numbers of MNPs/bacterium. There are also limited technologies to facilitate the selection of MTB with different magnetic contents, such as MTB with compromised and enhanced biomineralization ability. Here, we describe a magnetic microfluidic platform combined with transient cold/alkaline treatment to temporarily reduce the rapid flagellar motion of MTB without compromising their long-term proliferation and biomineralization ability for separating MTB on the basis of their magnetic contents. This strategy enables live MTB to be enriched, which, to the best of our knowledge, has not been achieved with another previously described magnetic microfluidic device that makes use of ferrofluid and heat. Our device also facilitates the high-throughput (25,000 cells/min) separation of wild-type Magnetospirillum gryphiswaldense (MSR-1) from nonmagnetic ΔmamAB MSR-1 mutants with a sensitivity of up to 80% and isolation purity of up to 95%, as confirmed with a gold-standard fluorescent-activated cell sorter (FACS) technique. This offers a 25-fold higher throughput than other previously described magnetic microfluidic platforms (1,000 cells/min). The device can also be used to isolate Magnetospirillum magneticum (AMB-1) mutants with different ranges of magnetosome numbers with efficiencies close to theoretical estimates. We believe this technology will facilitate the magnetic characterization of genetically engineered MTB for a variety of applications, including using MTB for large-scale, controlled MNP production.IMPORTANCE Our magnetic microfluidic technology can greatly facilitate biological applications with magnetotactic bacteria, from selection and screening to analysis. This technology will be of interest to microbiologists, chemists, and bioengineers who are interested in the biomineralization and selection of magnetotactic bacteria (MTB) for applications such as directed evolution and magnetogenetics.
