We present a novel image-based method to measure the on-chip microfluidic pressure and flow rate simultaneously by using the integrated optofluidic membrane interferometers (OMIs). The device was constructed with two layers of structured polydimethylsiloxa ...
The term of optofluidics defines an emergent research field that combines microfluidics and optics. In many lab-on-a-chip applications, these two technologies are used in combining the microfluidics for sample delivery and optics for sensing and controllin ...
We presented a pneumatically tunable 2 x 2 optofluidic switch for on-chip light routing that was controlled by compressed air. The device was fabricated with an optically clear elastomer-polydimethylsiloxane ( PDMS)-by soft-lithography. The optical switchi ...
Optical sensors based on the interaction between molecular vibrations and mid infrared radiations attracted high attentions in the last decades. In this study, we present the development of a waveguide evanescent field sensor based on the absorption spectr ...
SU-8 photoresist is commonly used in the field of microfabrication as structural material or for molding of microfluidic devices. One major limitation, however, is the difficulty to process partially freestanding SU-8 structures or monolithic closed caviti ...
The efficiency of on-chip microfluidic liquid-liquid extraction was improved by two orders of magnitude by spraying one liquid in another compared to the state-of-the-H-filters. We are developing a portable, integrated optical microsystem in the mid-infrar ...
In this work, we propose a unique plasmonic substrate that combine the strength of localized and extended surface plasmons for optical trapping, spectroscopy and biosensing, all in the same platform. The system is based on periodic arrays of gold nanopilla ...
We present an optofluidic chip with integrated polymer interferometers for measuring both the microfluidic air pressure and flow rate. The chip contains a microfluidic circuit and optical cavities on a polymer which was defined by soft lithography. The pre ...
We present an optical trapping system combining individually addressable multiple laser traps with fluorescence spectroscopy. An in-line set of 64 near-IR laser diodes is used to create a line of individually addressable traps inside a microfluidic chip. T ...
On-site drug testing using easily accessible body fluids, such as saliva, has gained a lot of importance both for road safety and forensic applications. However, saliva is a complex, inhomogeneous amalgam with many different compounds, whose concentrations ...
