A liquid tunable grating in a micro-optical fluidic system (MOFS) chip is demonstrated in this paper. The on-chip grating is realized through a microfluidic control system comprising of multilayer laminar flow. The liquid grating provides tuning possibility through the modulation of refractive index (RI) and grating pitch. The liquid tunable grating can be employed for accurate measurement of refractive...
This paper reports an analysis of the irreversible deposition of colloidal particles from the pressure-driven flow in a microchannel within the framework of DLVO theory. A theoretical model is presented on the basis of the stochastic Langevin equation, incorporating the random Brownian motion of colloidal particles. Brownian dynamics simulation is used to compute the particle deposition in terms of...
