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…
Error reduction in biosensors using secondary labeling
Tuhin Chakrabortty, Manoj M Varma
In this article, we derive the limit of detection for a two-step molecular recognition process and show that in-spite of all the recognition reactions being in equilibrium the over…
Fundamental Limitations in Biomarker Based Early Disease Diagnosis
Tuhin Chakrabortty, Chandra R. Murthy, Manoj Varma
Clinical biosensors with low detection limit hold significant promise in the early diagnosis of debilitating diseases. Recent progress in sensor development has led to the demonstr…
Tracking-free Determination of Microparticle Motion from Image Variance
Harish Sasikumar, Manoj M. Varma
In this work, we use the standard deviation of image pixel intensity to analyse the speed, direction and surface-interaction of microparticles in fluid. First, we present an analyt…
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…
