Fundamental limits of accuracy and precision in single molecule biosensors
Tuhin Chakrabortty, Manoj M Varma
Physical limit of molecular sensing has been extensively studied in biological systems. Biosensors are engineered equivalents of molecular sensors in living systems and play critic…
Equilibrium Probability Distribution for Number of Bound Receptor-Ligand Complexes
Tuhin Chakrabortty, Manoj M Varma
The phenomenon of molecular binding, where two molecules, referred to as a receptor and a ligand, bind together to form a ligand-receptor complex, is ubiquitous in biology and esse…
Theoretical Limit Of Concentration Sensing of Single Receptor Artificial Biosensors
Tuhin Chakrabortty, Manoj M Varma
Artificially engineered biosensors are highly inefficient in accurately measuring the concentration of biomarkers, particularly, during early diagnosis of diseases. On the other ha…
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…
A Null-model Exhibiting Synchronized Dynamics in Uncoupled Oscillators
Tuhin Chakrabortty, Akash Suman, Anjali Gupta +2
The phenomenon of phase synchronization of oscillatory systems arising out of feedback coupling is ubiquitous across physics and biology. In noisy, complex systems, one generally o…
