- W2029041454 abstract "Many microorganisms, including spermatozoa and forms of bacteria, oscillate or twist a hair-like flagella to swim. At this small scale, where locomotion is challenged by large viscous drag, organisms must generate time-irreversible deformations of their flagella to produce thrust. To date, there is no demonstration of a self propelled, synthetic flagellar swimmer operating at low Reynolds number. Here we report a microscale, biohybrid swimmer enabled by a unique fabrication process and a supporting slender-body hydrodynamics model. The swimmer consists of a polydimethylsiloxane filament with a short, rigid head and a long, slender tail on which cardiomyocytes are selectively cultured. The cardiomyocytes contract and deform the filament to propel the swimmer at 5–10 μm s−1, consistent with model predictions. We then demonstrate a two-tailed swimmer swimming at 81 μm s−1. This small-scale, elementary biohybrid swimmer can serve as a platform for more complex biological machines. Self-propelled biological microswimmers in viscous fluids are common in nature, but their synthetic counterparts are not available to date. Williams et al.develop a hybrid swimmer to emulate flagellar propulsion, which provides a platform to add engineered functionality to complex motile devices." @default.
