Numerical modeling of the formation of dynamically configurable L2 lens in a microchannel

Gupta A., Kitting J., Karampelas I.H., Flow Science Inc., US

The aim of this presentation is to describe the numerical modeling of a dynamically reconfigurable liquid-core liquid-cladding (L2) lens in a microfluidic channel, followed by a quantitative validation against the experimental results [1]. The lens [...]

An Integrated Optofluidic System for Two-Dimensional Focus Point Control

Chao K.-S., Lin M.-S., Yang R-J, National Cheng Kung University, TW

Recently, optical methods have been widely used for biological and chemical detection in microﬂuidic or lab-on-a-chip systems. Precise adjustment of the optical path among multiple integrated components, such as flow cytometers, optical tweezers, and molecule [...]

An optofluidic device for characterizing the effect of viscosity and density on mass transfer

Lapsley M.I., Nama N., Yazdi S., Huang T.J., Pennsylvania State University, US

In this study, we developed an optofluidic device for analyzing the mass transfer of materials in a microfluidic channel. This device uses refractometry to monitor concentration in contrast to typical methods which use florescent markers. [...]

Bio-inspired Optoelectronic Digital Nose

Bayindir M., Yildirim A., Vural M., Yaman M., Bilkent University, TR

We introduce and demonstrate the capabilities of a novel integrated optoelectronic-microfluidic sensor array that can rapidly distinguish millions of, trace level volatile chemicals based on their spectroscopic fingerprints inside flexible optofluidic channels. The system consists [...]
