Elastocapillary flow driven lab-on-a-membrane device based on differential wetting and sedimentation effect for blood plasma separation

Journal of Micromechanics and Microengineering, 2019
We report an elastocapillary flow—driven lab on a membrane device based on differential wetting and sedimentation effect for the separation of plasma from whole blood.

Highly sensitive and rapid isolation of fetal nucleated red blood cells with microbead-based selective sedimentation for non-invasive prenatal diagnostics

Nanotechnology, 2018
Non-invasive prenatal diagnostics (NIPD) has been an emerging field for prenatal diagnosis research. Carrying the whole genome coding of the fetus, fetal nucleated red blood cells (FNRBCs) have been pursued as a surrogate biomarker traveling around in ...

Electrochemical impedance spectroscopy of blood for sensitive detection of blood hematocrit, sedimentation and dielectric properties

, 2017
Electrochemical impedance spectroscopy (EIS) is a highly promising tool for the analysis of blood. The electrical properties of plasma and blood cells provide fundamental insights into the health status of patients. Nevertheless, the potential of EIS has

The behavior of sedimenting blood

Tubercle, 1939
Summary (1) During sedimentation blood is found to exhibit three phases, the first and last of which are incalculable. The phase of maximum velocity—the middle phase—is found to bear an exponential relationship to the amount of agglutinating substances (called ‘sedimentin’ for short) in the plasma.

Plasma levels of the leucocyte L1 protein in febrile conditions: relation to aetiology, number of leucocytes in blood, blood sedimentation reaction and C-reactive protein.

Scandinavian Journal of Clinical and Laboratory Investigation, 1984
Plasma levels of a novel leucocyte protein (L1) were determined in a series of 176 febrile patients and compared with CRP, BLC, and BSR. Among 82 patients with bacterial infection, 81 had L1 levels above the 0.95 interval.

The Sedimentation Rate

JAMA, 1968
The sedimentation rate measures the rate of fall of erythrocytes in the plasma. The rate is accelerated when alterations in plasma protein fractions cause rouleau formation or aggregation of red blood cells due to change in physicochemical properties of plasma and erythrocyte surfaces.

The mechanism of erythrocyte sedimentation. Part 1: Channeling in sedimenting blood

Colloids and Surfaces B: Biointerfaces, 2010
Despite extensive efforts to elucidate the mechanism of erythrocyte sedimentation, the understanding of this mechanism still remains obscure. In attempt to clarify this issue, we studied the effect of hematocrit (Hct) on the complex admittance of quiescent blood measured at different axial positions of the 2 mm x 2 mm cross-section chambers.

Sedimentation of single red blood cells

Soft Matter, 2013
The sedimentation of red blood cells (RBCs) due to gravitation or centrifugation at low Reynolds numbers is considered via computer simulations using multi-particle collision dynamics (MPC) and triangulated membranes. The RBCs assume different shapes depending on the elastic moduli of the cell membranes and the strength of the gravitation; these ...

SEDIMENTATION RATE OF THE BLOOD IN SCHIZOPHRENIA

Archives of Neurology And Psychiatry, 1933
As a part of a general investigation of the organic functions in schizophrenia (Hoskins and others1), a study was undertaken of the sedimentation rate of erythrocytes. For the past decade this reaction has been recognized as a sensitive index of damage to tissue or of infection.

A Modified Sedimentation Method for Counting Platelets in Blood

British Journal of Haematology, 1978
A sedimentation method for counting human blood platelets is proposed which uses a fluid of sp.gr. 1.057 at an osmolarity of 320 milliosmols. The fluid is a mixture of Lymphoprep and Isoton II. After centrifugation at about 200 g platelets are counted on an electronic particle counter.
