Cell viability assessment by flow cytometry using yeast as cell model

Philippe Renaud, Niccolo Piacentini, Raphaël Tornay, Nina Buffi

This paper reports the new combination of cell sorting and counting capabilities on a single device. Most state-of-the-art devices combining these technologies use optical techniques requiring complicated experimental setups and labeled samples. The use of ...

Optical Trapping in Microfluidic Channels for Functional and Chemical Analysis of Single Cells

Michael Werner

The physiological properties of cells are typically investigated in ensembles yielding averaged data that mask heterogeneities present in any cell population. Single-cell analysis techniques based on microfluidic "lab on a chip" (LOC) devices have recently ...

Fc Block Treatment, Dead Cells Exclusion, and Cell Aggregates Discrimination Concur to Prevent Phenotypical Artifacts in the Analysis of Subpopulations of Tumor-Infiltrating CD11b(+) Myelomonocytic Cells

It is well established that cancer cells can recruit CD11b(+) myeloid cells to promote tumor angiogenesis and tumor growth. Increasing interest has emerged on the identification of subpopulations of tumor-infiltrating CD11b(+) myeloid cells using flow cyto ...

A multi-color fast-switching microfluidic droplet dye laser

Demetri Psaltis

We describe a multi-color microfluidic dye laser operating in whispering gallery mode based on a train of alternating droplets containing solutions of different dyes; this laser is capable of switching the wavelength of its emission between 580 nm and 680 ...

Compartmentalization of Gold Nanocrystals in Polymer Microparticles using Electrohydrodynamic Co-Jetting

Francesco Stellacci

Polymer particles with micro- and nanoscale anisotropy have received increasing interest for their ability to simultaneously present different physical- and chemical properties. In this communication, we demonstrate that gold nanocrystals (NCs) can be sele ...

Analytical expression for electric filed between two facing strip electrodes in microchannels

Philippe Renaud, Olof Pontus Linderholm, Urban Seger

An analytical solution is presented for the electric field between two facing strip electrodes situated in a microchannel, as frequently used in impedance cytometry applications. The measured change in resistance as induced by a 5 mm bead moving through th ...
