TL;DR: A wide range of microfluidic technologies have been developed to separate and sort cells by taking advantage of differences in their intrinsic biophysical properties, including size, electrical polarizability, and hydrodynamic properties.

TL;DR: It is hoped that an improved fundamental and quantitative understanding of inertial fluid dynamic effects can lead to unprecedented capabilities to program fluid and particle flow towards automation of biomedicine, materials synthesis, and chemical process control.

TL;DR: Focusing on the dynamics of the particle–particle interactions reveals a mechanism for the dynamic self-assembly process; inertial lift forces and a parabolic flow field act together to stabilize interparticle spacings that otherwise would diverge to infinity due to viscous disturbance flows.

TL;DR: Chip-based microfluidic calorimeters capable of characterizing the heat of reaction of 3.5-nL samples with 4.2-nW resolution are reported, achieving excellent thermal resolution via on-chip vacuum encapsulation, which provides unprecedented thermal isolation of the minute microfluideic reaction chambers.

TL;DR: This work found that the broken symmetry of non-equilateral triangular channels leads to the shifting of focusing positions with varying Reynolds number, and by connecting channels with different cross-sectional shapes, was able to manipulate the accessible focusing positions and achieve focusing of microparticles to a single stream with ∼99% purity.
