    Single Cell Volume Measurement Utilizing the Fluorescence Exclusion Method (FXm)
    Authors:  Nash D. Rochman, Kai Yao, Nicolas A. Perez Gonzalez, Denis Wirtz and Sean X. Sun, date: 06/20/2020, view: 640, Q&A: 0
    [Abstract] The measurement of single cell size remains an obstacle towards a deeper understanding of cell growth control, tissue homeostasis, organogenesis, and a wide range of pathologies. Recent advances have placed a spotlight on the importance of cell volume in the regulation of fundamental cell signaling pathways including those known to orchestrate ...
    Straight Channel Microfluidic Chips for the Study of Platelet Adhesion under Flow
    Authors:  Alexander Dupuy, Lining Arnold Ju and Freda H Passam, date: 03/20/2019, view: 5489, Q&A: 0
    [Abstract] Microfluidic devices have become an integral method of cardiovascular research as they enable the study of shear force in biological processes, such as platelet function and thrombus formation. Furthermore, microfluidic chips offer the benefits of ex vivo testing of platelet adhesion using small amounts of blood or purified platelets. ...
    Fabrication and Use of the Dual-Flow-RootChip for the Imaging of Arabidopsis Roots in Asymmetric Microenvironments
    [Abstract] This protocol provides a detailed description of how to fabricate and use the dual-flow-RootChip (dfRootChip), a novel microfluidic platform for investigating root nutrition, root-microbe interactions and signaling and development in controlled asymmetric conditions. The dfRootChip was developed primarily to investigate how plants roots interact ...
    A Microfluidic Device for Massively Parallel, Whole-lifespan Imaging of Single Fission Yeast Cells
    Authors:  Stephen K Jones Jr, Eric C Spivey, James R Rybarski and Ilya J Finkelstein, date: 04/05/2018, view: 4521, Q&A: 0
    [Abstract] Whole-lifespan single-cell analysis has greatly increased our understanding of fundamental cellular processes such as cellular aging. To observe individual cells across their entire lifespan, all progeny must be removed from the growth medium, typically via manual microdissection. However, manual microdissection is laborious, low-throughput, and ...
    Microfluidic-based Time-kill Kinetic Assay
    Authors:  Nicole Billings, Roberto Rusconi, Roman Stocker and Katharina Ribbeck, date: 05/05/2014, view: 9287, Q&A: 0
    [Abstract] In many environments, bacteria favor a sessile, surface-attached community lifestyle. These communities, termed biofilms, are ubiquitous among many species of bacteria. In some cases, biofilms form under flow conditions. Flow chambers, and in particular microfluidic channels, can be used to observe biofilm development and physiological effects ...
    Determination of the Intracellular Calcium Concentration in Peritoneal Macrophages Using Microfluorimetry
    [Abstract] Calcium is one of the most important intracellular messengers in biological systems. Ca2+ microfluorimetry is a valuable tool to assess information about mechanisms involved in the regulation of intracellular Ca2+ levels in research on cells and in living tissues. In essence, the use of a dye that fluoresces in the presence ...
