Thermoresponsive Cationic Block Copolymer Brushes for Temperature-Modulated Stem Cell Separation.

Macromolecular rapid communications, 2020
Recently, cell separation methods have become important for preparing cells for transplantation therapy. In this study, a thermoresponsive cationic block copolymer brush is developed as an effective cell separation tool.

Enhanced mechanical properties and cell separation with thermal control of PIPAAm-brushed polymer-blend microfibers.

Journal of materials chemistry. B, 2020
We have developed thermoresponsive microfibers with improved mechanical properties and enhanced temperature modulated-cell separation. Microfiber substrates were electrospun using poly(4-vinylbenzyl chloride) (PVBC)-poly(n-butyl methacrylate) (PBMA ...

Dielectrophoretic separation of cells: Continuous separation

Biotechnology and Bioengineering, 1995
AbstractDielectrophoresis is the movement of particles in non‐uniform alternating and direct current (AC, DC) electric fields. When nonuniform electric fields are created between microelectrodes, cells will redistribute themselves around the electrodes, the force holding the cells in place dependig on the local electric field and on the electrical ...

Biophysics of cell separations

Quarterly Reviews of Biophysics, 1975
To the Chemist, it has long been second nature to work with separate, purified substances. Biochemists and molecular biologists have now largely achieved the same working position, with their powerful separation techniques of ultracentrifugation, electrophoresis, chromatography and the like.

A separability parameter for dielectrophoretic cell separation

ELECTROPHORESIS, 2013
In this study, a separability parameter is introduced to determine the selection of optimum operating parameters for DEP separation of a cell pair. The separability parameter is defined as a function of cells’ Clausius–Mossotti (CM) factors. T‐cell leukemia Jurkat and mouse melanoma B16 cells are tested to validate the separability parameter.

Cell separation: a review

Pathology, 1984
This review summarizes currently available techniques for cell separation. Techniques that exploit differences in physical properties of cells are widely used but have a number of limitations. Those that are based on differences in surface properties may more readily permit reproducible separation of a functionally homogeneous population of cells ...

Microfluidics for cell separation

Medical & Biological Engineering & Computing, 2010
The need for efficient cell separation, an essential preparatory step in many biological and medical assays, has led to the recent development of numerous microscale separation techniques. This review describes the current state-of-the-art in microfluidics-based cell separation techniques.

Cellulase and cell separation

Giornale botanico italiano, 1995
Abstract The involvement of cellulase (endo-b-l,4-glucanase, EC 3.2.1.4) in a number of different cell separation events which occur in higher plants has been well established. Besides their significance for the plant growth and differentiation, these events can be economically important since they also comprise softening of fleshy fruits and ...

Microelectrofluidic probe for sequential cell separation and patterning.

Lab on a Chip, 2019
Cell separation and patterning are of interest to several biological and medical applications including rare cell isolation and co-culture models. Numerous microfluidic devices have been used for cell separation and patterning, however, the typical ...

Synaptosomes and cell separation

Neuroscience, 1976
Publisher Summary When fractionating a complex tissue like brain, experiments should begin by separating it into its constituent cell classes. Any subcellular fraction prepared from brain is intrinsically heterogeneous as it is derived from several cell types.
