Feeders and Expellers, Two Types of Animalcules With Outboard Cilia, Have Distinct Surface Interactions
Praneet Prakash, Marco Vona, Raymond E. Goldstein
Within biological fluid dynamics, it is conventional to distinguish between "puller" and "pusher" microswimmers on the basis of the forward or aft location of the flagella relative…
Anti-Diffusion in an Algae-Bacteria Microcosm: Photosynthesis, Chemotaxis, and Expulsion
Praneet Prakash, Yasa Baig, Francois J. Peaudecerf +1
In Nature there are significant relationships known between microorganisms from two kingdoms of life, as in the supply of vitamin B by bacteria to algae. Such interactions m…
Contact Force Mediated Rapid Deposition of Colloidal Microspheres Flowing Over Microstructured Barriers
P. Prakash, A. Z. Abdulla, M. Varma
Deposition of particles while flowing past constrictions is a ubiquitous phenomenon observed in diverse systems. Some common examples are jamming of salt crystals near the orifice…
Phototgyrotactic concentration of a population of swimming microalgae across a porous layer
Praneet Prakash, Ottavio A. Croze
The light environment controls the swimming of microalgae through a light-seeking and avoiding behaviour, which is known as phototaxis. In this work, we exploit phototaxis to contr…
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…
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…
Trapping/Pinning of colloidal microspheres over glass substrate using surface features
Praneet Prakash, Manoj Varma
Suspensions of micro and nano particles made of Polystyrene, Poly(methyl methacrylate), Silicon dioxide etc. have been a standard model system to understand colloidal physics. . Th…
