Tuning the torque-speed characteristics of bacterial flagellar motor to enhance the swimming speed
Praneet Prakash, Amith Z. Abdulla, Varsha Singh +1
In a classic paper, Edward Purcell analysed the dynamics of flagellated bacterial swimmers and derived a geometrical relationship which optimizes the propulsion efficiency. Experim…
