Flagella of bacteria
WebThe bacterial flagellar motor is a reversible rotary nano-machine, about 45 nm in diameter, embedded in the bacterial cell envelope. It is powered by the flux of H+ or Na+ ions across the cytoplasmic membrane driven by an electrochemical gradient, the proton-motive force or the sodium-motive force. … WebArtificial bacterial flagella are nonbiological structures whose design is based on that of bacterial flagella.
