Sheathless Microflow Cytometry Using Viscoelastic Fluids [PDF]

Scientific Reports, 2017
AbstractMicroflow cytometry is a powerful technique for characterization of particles suspended in a solution. In this work, we present a microflow cytometer based on viscoelastic focusing. 3D single-line focusing of microparticles was achieved in a straight capillary using viscoelastic focusing which alleviated the need for sheath flow or any other ...
