Active carpets drive non-equilibrium diffusion and enhanced molecular fluxes
Guzmán-Lastra, Francisca [Univ Mayor, Fac Estudios Interdisciplinarios, Escuela Data Sci, Chile]; Lowen, Hartmut; Mathijssen, Arnold J. T. M. (NATURE PORTFOLIO, 2021-03-26)Biological activity is often highly concentrated on surfaces, across the scales from molecular motors and ciliary arrays to sessile and motile organisms. These 'active carpets' locally inject energy into their surrounding ... -
Nutrient Transport Driven by Microbial Active Carpets
Guzmán-Lastra, Francisca [Univ Mayor, Fac Ciencias, Av Manuel Montt 367, Santiago 7500994, Chile]; Mathijssen, Arnold J. T. M.; Kaiser, Andreas; Lowen, Hartmut (AMER PHYSICAL SOC, 2018)We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways to replenish nutrients that feed back into ...
