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…

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…
