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…
Detection Limit for Optically Sensing Specific Protein Interactions in Free-solution
Harish Sasikumar, Manoj M. Varma
Optical molecular sensing techniques are often limited by the refractive index change associated with the probed interactions. In this work, we present a closed form analytical mod…
Thermo-optic coefficient measurement of liquids using silicon photonic microring resonators
Prashanth R Prasad, Shankar K Selvaraja, Manoj Varma
On-chip measurement of thermo-optic coefficient (TOC) of samples along with on-chip temperature measurements can be used to compensate for thermal fluctuation induced noise in refr…
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…
Direct Optical Visualization of Water Transport across Polymer Nano-films
Swathi Suran, Manoj M. Varma
Gaining a detailed understanding of water transport behavior through ultra-thin polymer membranes is increasingly becoming necessary due to the recent interest in exploring applica…
