'Fuelled' motion: phoretic motility and collective behaviour of active colloids
Pierre Illien, Ramin Golestanian, Ayusman Sen
Designing microscopic and nanoscopic self-propelled particles and characterising their motion has become a major scientific challenge over the past decades. To this purpose, phoret…
Entanglement and weak interaction driven mobility of small molecules in polymer networks
Rajarshi Guha, Subhadip Ghosh, Darrell Velegol +3
Diffusive transport of small molecules within the internal structures of biological and synthetic material systems is complex because the crowded environment presents chemical and…
3-D Printed Swimming Microtori for Cargo Transport and Flow Manipulation
Remmi Baker, Thomas Montenegro-Johnson, Anton D. Sediako +4
Through billions of years of evolution, microorganisms mastered unique swimming behaviors to thrive in complex fluid environments. Limitations in nanofabrication have thus far hind…
A Theory of Enzyme Chemotaxis: Comparison Between Experiment and Model
Farzad Mohajerani, Xi Zhao, Ambika Somasundar +2
Enzymes show two distinct transport behaviors in the presence of their substrates in solution. First, their diffusivity enhances with increasing substrate concentration. In additio…
Exothermicity is not a necessary condition for enhanced diffusion of enzymes
Pierre Illien, Xi Zhao, Krishna K. Dey +3
Recent experiments have revealed that the diffusivity of exothermic and fast enzymes is enhanced when they are catalytically active, and different physical mechanisms have been exp…
Distinguishing Advective and Powered Motion in Self-Propelled Colloids
Young-Moo Byun, Paul E. Lammert, Yiying Hong +2
Self-powered motion in catalytic colloidal particles provides a compelling example of active matter, i.e. systems that engage in single-particle and collective behavior far from eq…
