. 2015 Dec;
118(20):203904.
PMID: 26648596
We investigate the non-linear dynamics of superparamagnetic beads moving around the periphery of patterned magnetic disks in the presence of an in-plane rotating magnetic field. Three different dynamical regimes are...

Adv Mater
. 2015 Sep;
27(40):6176-80.
PMID: 26349853
The switching thresholds of magnetophoretic transistors for sorting cells in microfluidic environments are characterized. The transistor operating conditions require short 20-30 mA pulses of electrical current. By demonstrating both attractive...

Two-dimensional spatial manipulation of microparticles in continuous flows in acoustofluidic systems
Gao L, Wyatt Shields 4th C, Johnson L, Graves S, Yellen B, Lopez G
Biomicrofluidics
. 2015 Feb;
9(1):014105.
PMID: 25713687
We report a modeling and experimental study of techniques to acoustically focus particles flowing through a microfluidic channel. Our theoretical model differs from prior works in that we solve an...

Soft Matter
. 2015 Feb;
11(12):2404-15.
PMID: 25677504
Phase transformations can be difficult to characterize at the microscopic level due to the inability to directly observe individual atomic motions. Model colloidal systems, by contrast, permit the direct observation...

PMID: 25379081
We present a simple microchip device consisting of an overlaid pattern of micromagnets and microwells capable of capturing magnetically labeled cells into well-defined compartments (with accuracies >95%). Its flexible design...
