Rapid accumulation of colloidal microspheres flowing over microfabricated barriers
P. Prakash, A. Z. Abdulla, M. Varma
Accumulation of particles while flowing past constrictions is a ubiquitous phenomenon observed in diverse systems. Some of the common examples are jamming of salt crystals near the…
Swimming statistics of cargo-loaded single bacteria
P. Prakash, A. Z. Abdulla, V. Singh +1
Burgeoning interest in the area of bacteria-powered micro robotic systems prompted us to study the dynamics of cargo transport by single bacteria. In this paper, we have studied th…
Active modulation of surfactant driven flow instabilities by swarming bacteria
Harshitha S. Kotian, Shalini Harkar, Shubham Joge +4
Models based on surfactant driven instabilities have been employed to describe pattern formation by swarming bacteria. However, by definition, such models cannot account for the ef…
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…
