Microfluidic pumping using artificial magnetic cilia
Srinivas Hanasoge, Peter J. Hesketh, Alexander Alexeev
One of the vital functions of naturally occurring cilia is fluid transport. Biological cilia use spatially asymmetric strokes to generate a net fluid flow that can be utilized for…
Extreme thermodynamics with polymer gel tori: harnessing thermodynamic instabilities to induce large-scale deformations
Ya-Wen Chang, Michael S. Dimitriyev, Anton Souslov +5
When a swollen, thermoresponsive polymer gel is heated in a solvent bath, it expels solvent and deswells. When this heating is slow, deswelling proceeds homogeneously, as observed…
Asymmetric motion of magnetically actuated artificial cilia
Srinivas Hanasoge, Matthew Ballard, Peter J. Hesketh +1
Most microorganisms use hair-like cilia with asymmetric beating to perform vital bio-physical processes. In this paper, we demonstrate a novel fabrication method for creating magne…
Metachronal motion of artificial magnetic cilia
Srinivas Hanasoge, Peter J. Hesketh, Alexander Alexeev
Organisms use hair-like cilia that beat in a metachronal fashion to actively transport fluid and suspended particles. Metachronal motion emerges due to a phase difference between b…
Ants as Fluids: Physics-Inspired Biology
Micah Streiff, Nathan Mlot, Sho Shinotsuka +2
Fire ants use their claws to grip diverse surfaces, including each other. As a result of their mutual adhesion and large numbers, ant colonies flow like inanimate fluids. In this s…
