Journal ArticleDOI
Micromachined impedance spectroscopy flow cytometer for cell analysis and particle sizing
TL;DR: The microfabrication and characterisation of an on-chip flow-cytometer is described as the first building block of a complete cell-sorting device and the signal conditioning technique and impedance measurements of cells and particles of different sizes and types are discussed to demonstrate the differentiation of subpopulations in a mixed sample.
Journal ArticleDOI
Impedance spectroscopy flow cytometry: On‐chip label‐free cell differentiation
TL;DR: The microfabricated impedance spectroscopy flow cytometer used in this study permits rapid dielectric characterization of a cell population with a simple microfluidic channel and can be used for discrimination between different cell populations without the use of cell markers.
Journal ArticleDOI
Single cell dielectric spectroscopy
TL;DR: In this article, a review of single cell dielectric spectroscopy methods is presented, including ac electrokinetic methods of dielectrophoresis and electrorotation.
Journal ArticleDOI
Dielectric spectroscopy in a micromachined flow cytometer: theoretical and practical considerations
TL;DR: A model to determine the influence of different cell properties, such as size, membrane capacitance and cytoplasm conductivity, on the impedance spectrum as measured in a microfabricated cytometer is proposed.
Journal ArticleDOI
High speed multi-frequency impedance analysis of single particles in a microfluidic cytometer using maximum length sequences
TL;DR: It is demonstrated that the MLS technique can give multi-frequency (broad-band) measurement in a short time period and good agreement is shown between the MLS data and both circuit simulations and conventional AC single frequency measurements.
